SOURCE: TI-15 square root Function

Hello,
You should enter it as follows [SQRT]36 ) [ENTER/=].
If you define some function f of a variable x you write that f(x), where the parentheses enclose the so-called argument (objet on wich the function acts). It seems that on this calculator the opening parenthesis is implicit: the calculator supplies it when you press [SQRT] but does not display it (a design flaw?). However the closing parenthesis must be entered by you to signifie to the function [SQRT] that you have finished entering the argument. Weird but one can live with it.
Hope it helps.

Hello,
The question is not clear. What is the value of y?. The calculator cannot help if y is not known. I will give you a few hints for this algebra problem:
1. Taking the square root is equivalent to raising to the 1/2 power.
2. Power of a product is equal to the product of the powers. (X*Y)^a=(X^a) times (Y^a)
3. (X^a)^b =X^ (a*b)

Hope it helps.

SOURCE: Square root

It may be that you have somehow changed to a 'mode' that only shows integer values.

Try pressing the green button, then 5, then 9. Then try the calculation again.

If this fails, you can use Google as a calculator - search Google for sqrt(0.4053) and see what happens.. :-)

Use the square-root key just to the left of the divide key.

To calculate the square root of 9, press
2nd [square-root] 9 ) =

The square-root is the shifted function of the x-squared key, just to the left of the 7 key. The close-parenthesis is needed to balance the open-parenthesis automatically inserted by the square-root function.

### How do I do math problems estimate roots

To do them it REALLY helps if you remember Perfect Squares.it will make you quicker at doing these problems.

I have copied a section below.

For these problems.....
you don't need the exact answer! An approximation is good enough

. Memorize Squares

For all sorts of reasons, you should memorize perfect squares at least up to 12^2 = 144. It helps to know additional round numbers, such as 15^2 = 225 and 25^2 = 625.
Once squares are burned into your memory, estimating square roots is easy. Let's go back to the square root of 39. The nearest perfect squares are 36 and 49, which are squares of 6 and 7, respectively. Thus, the square root of 39 is somewhere between 6 and 7. Since 39 is closer to 36 than to 49, the square root of 39 is closer to 6 than 7.
Sure enough, the square root of 39 is about 6.24. You will never see a problem on the GMAT where you need to know that the square root of 39 is 6.24. But you may well need to know that the square root of 39 is a little bigger than 6.

We all had to learn these at one time.

Give it a go friend :) You won't regret it.later on in life.
