8 times the square root of 5

square root of 8*square root of *4 = 32 Sq root of 4=2 so its 2sq root 8

To get the square root of 8, you have to multiply the root of 2 and the root of 4. The root of 4 then simplifies to 2, so the square root of 8 equals 2 times the square root of 2.

√16 x √8 = 4 x 2√2 = 8√2 in radical form or as a decimal = ±11.3137085

It is 24*sqrt(3).

You look for a perfect square and take it out of the radical (while taking the square root of it).

Square roots, simplifiedWhen you are asked for a simplified square root of some number, the answer is expected to be in radical form, not in decimal form. For example, 3 radical 2 (or three square roots of two) is the simplified square root of 18.So, let's look at this one: the square root of 8.The factors of 8 are 4 and 2. (8 and 1 are also factors, but those are not helpful.) So we can say that the square root of 8 is equal to the square root of (4 times 2):SQT(8) = SQT(4 * 2)This can be written another way:SQT(8) = SQT(4) * SQT(2)Since 4 is a perfect square whose square root is 2, we can write the equation above this way:SQT(8) = 2 * SQT(2)In English, that's "The square root of 8 is 2 square roots of 2" or "The square root of 8 is 2 times the square root of 2" or "The square root of 8 is 2 radical 2."What's this radical business? Well, I can't draw the radical sign here, so I've been using the SQT(x) convention. That is equal to an x under a radical sign.By the way, 2 times the square root of 2 is 2.828, if you are wondering.

320 = 64(5) =8 radical 5.,,....or 8 times the square root of 5!

Â±3*sqrt(5) or Â±13*sqrt(5)

8√3

The square root of 64 is 8, which is a rational number.

sqrt(8) = sqrt(4 x 2) = sqrt(4) x sqrt(2) = 2xsqrt(2)

The square root of -8 is sqrt(8)*i where i is the imaginary square root of -1. It can also be written as 2*sqrt(2)*i - which looks a bit neater when the radical sign is used. That is, unfortunately, not possible with this browser.

The square root of 8 is 2 sqrt 2, an irrational number. In decimal form it is 2.828427124746190097603377448419...

8

Factor under the radical. sqrt(72) sqrt(3^2 * 8) 3sqrt(8) 3sqrt(2^2 * 2) 6sqrt(2) check and you see that sqrt(72) and 6sqrt(2) are equivalent

The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8

It might be best to answer this with an example. Look at the square root of 8. To simplify it we notice that 8 is 2x4 and that 4 is a perfect square. So we can simplify the square root by taking the 4 out of the radical sign and writing it as 2xsquare root of 2. Perhaps a better way to think of this is that is you have square root of a x square root of b, that is the square root of (ab). So if we have square root of 8 that is the same as square root of 4 x square root of 2 and square root of 4 is 2 so the answer is 2xsquare root of 2. In general, look for perfect squares and factor them out of the number so they can be removed from the square root.

Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)

It is rational because its square root can be expressed as a fracion in the form of 8/5

There is no "8 square root" of something. You can calculate the square root, or the 8th. root, of something.
