Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH
Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.

    To square the number multiply it by itself.
    -1.5 * -1.5 = +2.25

You're not calculating the square of a negative number, you're calculating the negative of a square. You need to use parenthesis to indicate the square of a negative number.

You're calculating -(3^2), not (-3)^2.

To calculate the latter: ( (-) 3 ) x^2 =

SOURCE: negative answer when squaring a neg number

You must put all negative numbers in Parenthesis otherwise your calculator is not squaring the negative .

SOURCE: Wrong answer with squared negatives.

Your calculator will square a number before it applies the negative sign, so what you're actually doing is squaring 2, then applying the - sign to your answer. You need to put the -2 in parenthesis, so (-2)^2. That will give you 4. Hope this helps!

How do I to convert from fraction to radical form on the TI-84


Sorry you cannot do that in any calculator. A fraction is a rational number, a root of any index is GENERALLY an irrational number. Some exceptions do exist, but in general NO.
Square root (9/16) =3/4

How to put negative fractional power to BA11 plus calculator or how to solve with formula.


Put the fraction inside parentheses so the division occurs before the power, and use the +/- key instead of the - key to enter a negative number. For example, to calculate 8 raised to the minus one-third, press 8 y^x ( 1 +/- 3 ) =. You should get 0.50.

My ti-83 stop changing decimals to fraction


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.

Mixed numbers


If the result is positive, type in the integer part then add the fraction part either with the help of the fraction key or the division key. (I do not think that the TI82 has a fraction key.
If it is anything like the TI3 there is command under MATH >Frac. It should be pressed after you enter the mixed number to keep the result as a fraction.
If the mixed number is negative you enclose the whole number in parentheses. Press the change sign (-) key to negate the result.

3/8-7/2= how do I get the answer I know the answer but want to know hot to get it


You convert the fractions so they have the same denominator (bottom number) then subtract the numerators (top numbers). 7/2 is the same as 28/8 (8 divided by 2 = 4. 4 times 7 = 28, so the equivalent fraction is 28/8. You can check by dividing 8 into 28 = 3 1/2 = 7/2. So, 3/8 - 28/8 = negative 25/8 or 3 1/8.

How do i convert the answer of cos(30) which comes out to 0.8660254038 to a fraction?


I am sorry, my friend, but you are asking the impossible. The reason is that the exact value of cos(30 deg) is equal to square root (3) /2 which cannot be fraction (the square root of 3 is an irrational number).
However, it may be possible for your calculator to give you a result with a radical (3)/ 2 but that is no fraction. (A fraction must have both numerator and denominator as integers).

To get a radical result set the IO mode to MathIO.
Press [SHIFT] [MODE] to open (SETUP) and select [1:MathIO]

Want to know how to calculate a number raised to a power


Use the general power key marked with X to the y ( look for the image of a key on same line as Power in the screen capture)
You enter a number then press the power key and finally the exponent. If exponent is complicated (fraction, negative or other) enclose the exponent in parentheses.

How to use the exponent key on a casio fx 300ES calculator ?


The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
  1. You enter the base (the number to be raised to a power).
  2. You press the [X to ] power key.
  3. You close the parenthesis (the right one).
  4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]
