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.

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.. :-)

To calculate a square root you press the square root key. A radical will be displayed. You type in the positive number whose root you want. Press the EXE key.

I got the FX-9860GII and it shows up as decimal aswell, how do I change it?

I assume you want to round it to the nearest thousandth.

Step 1 - identify the thousandths column - going to the right of the decimal are tenths, than hundredths, than thousandths

Step 2 - check the number immediately to the right of this column

Step 3 - if this number is 5 or greater, add 1 to the thousandths column

Step 4 - if this number is 4 or less - no nothing

Step 5 - delete all numbers to the right of the thousandths column

In this case the 8 is greater than or equal to 5, so we add 1 to the 6 to get 7 and then delete all the numbers to the right.

I get 7.247.

Good luck.

3.51795813

0.12345678

See the above line. The numbers relate to negative powers of ten.

1/1000 is 1x 10-3

Therefore the nearest thousandth is to three decimal places, which is 3.517, though since it is followed by a nine, which is greater than 4, the 7 then has 1 added to it and becomes 8.

The answer, therefore is 3.518.

Do nothing. The number is already rounded to the nearest thousandths.

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

From this page http://www.gmathacks.com/mental-math/estimating-square-roots.html

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.

The square root of 7750 is about 88.

Jun 26, 2014 | Office Equipment & Supplies

To the nearest thousandth, it's 24,270 (or to be more precise, 24,270.000).

To the nearest thousands, it's 24,000 (twenty-four thousand).

To the nearest thousands, it's 24,000 (twenty-four thousand).

Step 1 - identify the thousandths column - going to the right of the decimal point, we have the tenths column, the hundredths column, and the thousandths column

Step 2 - check the number immediately to the right of this column

Step 3 - if this number is 5 or more, add 1 to the thousandths column - if this number is 4 or less, don't add 1 to the thousandths column (leave it alone)

Step 4 - erase all the numbers to the right of the thousandths column.

In this case, the number in the thousandths column is 4. The number immediately to the right of it is a 0. Since the 0 is 4 or less, we don't add 1 to the thousandths column. Now we erase all numbers to the right of the thousandths column. I get 22.524.

Good luck.

Round to three digits after the decimal point, so this is 2.442 .

The first digit after the decimal point is the tenths, the second the hundredths, and the third the thousandths.

Do you mean round off to the nearest thousandths? The thousandths place is the third place to the right of the decimal point. An example would be 0.001. In this case you have a 1 in the thousandths places which would be stated as one thousandth. To round to the nearest thousandths place you would look at the number in the ten-thousandths place and use that to determine what the number in the thousandths place should be. For example, if you have a number such as 0.1234 your answer, rounded to the nearest thousandth would be 0.123 because 4 is less than 5 and therefore you would round down. If you have a number such as 0.1235 your answer would be 0.124 because you always round up if the number in the next decimal place is 5 or higher.

I hope this helps.
