How do i work out square and cube numbers on this calculator?

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

It can handle square root but if result requires too much display space it will be displayed as a decimal.As to higher order roots such as cube , 4th and higher they are displayed as decimal. Sorry, there is nothing you can do about it.

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 =

There's a cube root function in the MATH menu. Press the MATH key and it should be item 4.

Two buttons under the shift key-(top left key) and to the right one is the square root key. Just push it and put the number in...it is not manditory to close the parentesis. You can also hit shift before the square root key to get the cubed root.

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)

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 [=]

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

root(8,3)

root(8,3)

x-th root of a number equals the number to the power of (1/x) where x is a natural number.

square root = to the power of (1/2)

cubic root = to the power of (1/3)

square root = to the power of (1/2)

cubic root = to the power of (1/3)

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.
