The square root of 8 is 2 multiplied by the square root of 2
Sq root of 2 * sq root of 8 = 1.414 * 2.828 = 3.998792
It is: 2 times the square root of 2
it is the square root of 16 which equals 4.
=SQRT(5)*SQRT(2)+SQRT(8) is 5.99070478491457
The square root of 8 is 2 times the square root of 2 sqrt(8) = 2 x sqrt(2)
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.

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

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
7*square root of 8.
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.

square root of 8*square root of *4 = 32 Sq root of 4=2 so its 2sq root 8
Root 64 is 8, if by root you mean the square root. Then the problem become -square root 84(6+8) which is the - square root of 84(14) But square root of 84 is 2(square root of 21) so the final answer comes from -2(square root 21)x14 which is -28square root (21)
