Square root of 39: Press 3 9 [square-root] =

[square-root] is the key just to the left of the divide key.

Cube root of 9482: Press 9 4 8 2 2nd [cube-root] =

[cube-root] is the shifted function of the 0 key.

For other roots, you can use the [nth-root] function, the shifted function of the key above the divide key. For example, to calculate the fourth root of 16, press 1 6 2nd [nth-root] 4 =

Almost exactly the way it's written in the book.

In the LineIO mode press

3 SHIFT [xth-root] 5 0 0 0 * 3 / ( 4 * SHIFT [pi] ) ) =

In the MathIO mode press

SHIFT [xth-root] 3 right-arrow 5 0 0 0 * 3 / ( 4 * SHIFT [pi]) =

xth-root is the shifted function of the key just below and right of the big round cursor pad.

* is the multiply key

/ is the divide key

pi is the shifted function of the x10^x key in the middle of the bottom row

BTW there's no "square root" in this problem. There's a "cube root" or "third root". Square root is the second root.

For cube roots, use the cube-root function in the MATH menu. For example, to calculate the cube root of 8, press MATH 4 8 =

For other roots (including cube root), use the xth-root function in the MATH menu. For example, to calculate the fifth root of 32, press 5 MATH 4 3 2 =

You can calculate any root by raising to the reciprocal. For example, to calculate the cube root of 125, press 1 2 5 y^x 3 1/x =

To calculate the fourth root of 16, press 1 6 y^x 4 1/x =

The y^x key is just above the 9 key. The 1/x key is just above that.

To calculate the fourth root of 16, press 1 6 y^x 4 1/x =

The y^x key is just above the 9 key. The 1/x key is just above that.

Press the MATH key to bring up the Math menu. Option 3 gives you cubed, option 4 gives you cube root, option 5 gives you nth root.

For example, 3rd root of 8: MATH 4 8 ENTER gives 2.

4th root of 16: 4 MATH 5 16 ENTER gives 2.

For example, 3rd root of 8: MATH 4 8 ENTER gives 2.

Power 1/2 is the same as square root: You can use the square root key to the left of the square key.

Similarly power 1/3 is the cube root. You use the [SHIFT][Square root] key sequence.

Power 2/3 is the square of the cube root, or the cube root of the square.

More generally, you can use the universal power key, marked with X with a raised white rectangle. It is between X square and log.

Ex: Calculate 15^(2/3)

15 [X with raised rectangle] 2 [/] 3 [)] [=]; the result is 6.082

The last parenthesis closes the left parenthesis introduced by the calculator.

Alternatively you can use the cube root and the x-root selections available under the MATH menu.(selections 4 and 5)

Hello,

What we call roots: square, cube ,fourth roots, etc. can be shown in algebra to be equiavlent to powers with fractionary exponents where numerator is 1 and denomonator an integer.

**square root of a = a to the power 1/2**

**cube root of a = a to the power 1/3**

**n-th root of a = a raised to the power 1/n,** n integer different from 0.

How to use calculator to calculate cube root?

If you do not have a specific (shortcut) key for it you use the key to raise to an arbitrary power [^ ], sometimes shown as [x^y]. The exponent will be 1/3. Do not replace 1/3 by its decimal approximate.

Cube root of 27 is entered as**27 [^ ] (1/3)**

Hope it helps.

You use the y^x (y to the x) key along with the 2nd function key. That does the opposite operation.

So, let's pick something we know the answer to as an example. How about the cube root of 8? We know 8 = 2 X 2 X 2, so the cube root of 8 will be 2.

Here's how:

8 2nd y^x 3 =

The display will show 2.

The three is the root you want. You can put in any number, with 2 being the square root, 3 the cube root, etc.
