To get an exponent press 2nd then LN or LOG

LN is natural logs, so entering 1 then 2nd LN gives you the natural exponent of 1 which is.2.71828....pressing LN gives you the natural log of 2.71828.... which is 1

LOG is logs to base 10, so entering 1 then 2nd LN gives you the 10 to the power 1 which
is.10, pressing LOG gives you the log of 10 which is 1 again

We are asking what number, times itself, is equal to 30. Five times itself is 25. Six times itself is 36. The answer is somewhere between 5 and 6. Let's split the difference and try 5.5. 5.5 times 5.5 is 30.25. This is above 30, so let's try a smaller number, 5.4. 5.4 times 5.4 is 29.16. This is lower than 30, so we need a higher number. How about 5.45? I get 29.7025. We need a number a little higher. How about 5.47? I get 29.9209. Still need a little higher. How about 5.48? 30.0304. So it is somewhere between 5.47 and 5.48.

On a calculator, you can use the square root function. Sometimes you have to enter the number before you hit the square root function and sometimes you need to enter the number after hitting the square root function. Another way of doing it is to use the exponent function, usually with a y to the x key or a ^ key. Enter 30, hit the exponent key, and then enter 1 divided by 2 in brackets.

I get approximately 5.477225575051661134569697828008.

Good luck.

Use the square root key. For roots of higher index, use the xRoot key; the shifted function of the Y^x or [^] with exponent 1/3 for cube root, 1/4 for 4th root, or 1/n for the n-th root.

Use the xth-root function in the MATH menu (it should be the fifth item). For example, to calculate the 15th root of 2, press 1 5 MATH 5 2 ENTER .

I come up with 3. (81^(1/2))^(1/2)=3. the Simplest form. I used 81^(1/2) because, 81 looks like 81 to the first power, instead of a fraction.

Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

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.

You aslo have dedicated keys for certain powers and roots (square, square rooot, cube, cubic root)

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).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).

- You enter the base (the number to be raised to a power).
- You press the [X to ] power key.
- You close the parenthesis (the right one).
- You press [=]

- Use the universal power key marked with [^].
- To avoid problems if the exponent is an expression, enclose it in parentheses.
- To enter any power type number^(exponent)
- If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
- To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
- Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

To find the cubed root of say...8, then you would type this into the calculator:

root(8,3)

root(8,3)
