What number ^2 (squared) equals 512?

Question

What # ^2 (squared) equals 512? I know there is a simple way to answer this but I have no idea what it is!! Thanks in advance!

Answer 1

You mean the square root of 512? That would be the simplest way of saying it. Though you can simplify the square root:
√512 = √(4*128) = √(4*4*32) = 4√(16*2) = 4*4√2 = 16√2

I could pull out the calculator and give a round-off decimal answer to this (which I see some people are trying to pass off as the exact value), but why bother.

Answer 2

The number, when squared, that equals 512 is called the square root of 512. You can just use the square root button on your calculator.

The number is 22.62741799796952...... by the way.

Answer 3

2 Squared Equals

Answer 4

This is a pretty tricky question. Under normal circumstances, no. The data held inside the byte will be the same if you were to have two identical bytes. Example: Byte 0 (single byte) = 2. Byte 1 / 2= 2 Byte 0^2 = 4. Byte 1 * byte 2 = 4. In the event that byte 1/2 are not equal, this is false, so under non-special circumstances I would say this is false. The way these are calculated is known as hexidecimal multiplication. In this case, let's assume for a moment that 255 is stored in byte 1. This is an 8 bit value and would be represented by the hex FF (16 / 16. and in this case 16*16 = 255 (since it's a set of numbers including 0, thus 255 is the 256th position)) . Then you take the value stored in the first byte and multiply it by the second. Example, FF (255) * AD (173) = AC53 (44,115) if you run windows 7 you can switch the in-OS calc to "Programmer", then change it to hex and back to dec to get a better feel for this.

Answer 5

None. Since 2^9=512 and 9 is odd, no multiple of 2 is a square root of 512. The nearest squares are 484 (22) and 529 (23).

Answer 6

Asking what number (squared) is equal to 512, is the same as asking, "What is the square root of 512?"

While I can do square roots by hand, it's cumbersome to explain. Since most calculators have a square root function, I'll refer you to a calculator instead of putting you to sleep with the manual verson.

When I use my calculator I get the square root of 512 is 22.62741699797.

You can double check by multiplying the number by itself and see if its' reasonable.

(22.62741699797 * 22.62741699797) = 512.00000000001

Answer 7

take you calculater and plug in 512, then there will most likely be a shift button and a yellow or blue, or some other color square root button above another button. After you hit shift, hit that button, and it will tell you the answer. If you have a really sophisticated calculator, you might put in the square root button first then put 512 in. Do this with all the square roots and you'll be happy.

Answer 8

take the square root of 512.

Answer 9

just take the square root for 512
it is 16 square rt 2
or22.63
