Use the general power key that is marked as [^], [Y^x] or [X^y]. Enclose the fractional exponent (1/3) in parentheses.

You can also look for a general root key, marked as [x Root]. To use this key, press the root index (3 for example), followed by [x Root] and then enter the argument. If the index of the root is even ( 2, 4, 6, ...) the argument (inside the root) must be a positive number.

Roots are called as follows:

square root

cube /cubic root

From 4th on, use the ordinal fifth, sixth, ... n-th

To calculate the fourth root you have two possibilities.

To calculate the fourth root you have two possibilities.

- Some calculators have the x-root key marked with an x followed by the radical symbol. See the screen capture on how to find your result.

Usually the x-root is the SHIFTED function of the general power key that is marked ( [^], [X^y], or [Y^x] ). To use it, you inter the index of the root (the ordinal number). then you press the [SHIFT/2nd/ 2nd] [X^y] sequence and the number whose root you are calculating). - Alternatively: Use the equivalence
**n-th Root (x)=x^(1/n)**, meaning that**to extract the fourth root of 16, you raise 16 to the power of (1/4)**

The Frac command only works if the number can be expressed as a fraction with no more than three digits in the denominator. Since the square root of 5/9 is an irrational number, it cannot be expressed as a fraction at all. The calculator is telling you that the value cannot be adequately approximated as a fraction with three or fewer digits in the denominator.

Your expression is ambiguous: There is a function named int( which extracts the integer part of a numerical result. But there is nothing enlightening about it: int(25/3) gives 8 as result

Do you mean to calculate the integral?

Is it arc sin of square root of X or square root of arcsin(X)?

I am going to assume you want to calculate the indefinite integral of [arcsin (square root of X)]/(1-X)^(1/2)

In Main calculator screen tap the Down pointing arrow at the left of the tool bar (left of the Edit Menu). Select Settings>SetUp>Basic Format

As you can see, the angle unit must be in Radians. Make sure that the Decimal calculation is unchecked, otherwise yoy will get a numerical result.

Press the keyboard key to enter your expression.

Press the keyboard key to enter your expression.

- Press the 2D keyboard
- Use the pen to tap the arrow close to the 0 to reveal the Integral template and tap it
- Tap the arrow again to reveal the fraction template.
- Tap it to insert it at the cursor position.
- Tap mth to open the mathematics tab
- At the bottom of the mth Tab press TRIG
- Tap the arc sine key (sin^-1) and insert it in the numerator of the fraction.
- Press the U-turn arrow at the bottom of the mth keyboard to exit the trigonometric functions.
- Tap the square root function to the right of the natural log, tap the variable x and right parenthesis, on physical or soft keyboards.
- Tap the down arrow to move cursor to the denominator of the integrand.
- Type in the denominator (square root of (1-x))
- Use the right arrow to move the cursor to main line, and one more tap to move cursor after the d, press the x key enter the differential.

Sorry, but the calculator is working as it should. Read on till the end, you will understand how to use it to suit your needs,

If you do not want to see fractions and radicals ( roots) anymore just set the calculator Input/Output mode to LineIO:

Press [SHIFT][MODE](SETUP) and select [2:LineIO].

If, however, you appreciate the functionalities of the MathIO that allow you to manipulate fractions, radicals, and other nifty things you could not do before, but just want your final results to be in decimal format that can be arranged too.

Here is how

Here is how

- Set the I/O mode to MtahIO: Press [SHIFT][MODE][1:MthIO]
- Enter your expressions, and when you are finished press [SHIFT][=]. Your result will be in decimal format.
- Alternatively, you can calculate your result in MthIO and convert the fractions/radicals to decimals by pressing the [S<=>D] key, the one located between the [)] and the [M+] keys.
- Every time you press that key you toggle the display from fractions/radicals to decimal and back.

Hi shiny_diamon

Here is a picture of the powers and root functions of your calculator.

1.To calculate the cubic root of a number you use the key combination shown on line 5

Ex: Cubic root of 27

27 [2nd] [3 root x] [EXE]; Should get 3

2. You can use the general root key on line 7 [2nd][x Root y]

Ex: Cubic root of 125

125 [2nd][ x Root y] 3 [EXE] Should get 5

(-125) [2nd][x Root y] 3 [EXE]; Should get -5

3. You can also yse the general power key on line 6: [Y to x], but the degree of the root is entered as a fraction 1/3

Ex: cubic root of -125.

(-125) [Y to x]( 1/3) [EXE]; You should get -5

**4. The [Y to x[ key is the one you use to obtain all other roots fourth, fift, tenth, n-th.**

Ex: Fourth root of 256

256 [Y to x] (1/4) [EXE]: You should get 4

Hope that helps.

Hello,

When you calculate the** product** 7.4 x2, the calculator gives you a fraction reduced to it simplest terms, 74/5 . The result is correct, but it happens that you want it
expressed as a decimal rather than a fraction. To fix that all you have
to do is to press the button **[S<->D] ** above the red [DEL] key. It allows you to toggle the display format between fraction and decimal.

74/5 [S<->D] changes display to 14.8 and if you press the key again you go back to fraction

14.8 [S<->D] 74/5

Similarly, if you enter square root of 2 and it displays as a radical, you convert it to a decimal by pressing the key [S<->D].

The fraction and radical formats allow you to do exact claculations. But if you do not want to hear about that you can just press [SHIFT][MODE][2:LineIO] : Your calculator will do things the old way, but you will lose some important functionalities.

My suggestion is to set the default mode [MathIO] by pressing [SHIFT][MODE][MathIO] and to press the [S<->D] key to convert to decimal.

Hope it helps.
