7.135 * * * * * sqrt(18)*sqrt(8) = sqrt(18*8) = sqrt(144) =12
square root 2 times square root 3 times square root 8
sqrt(18) - sqrt(8) = sqrt(2)
The square root of 8 is 2 times the square root of 2 sqrt(8) = 2 x sqrt(2)
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.

It could be: 7/8 times 7/18 = 49/144 and its square root is 7/12
square root 2 times square root 3 times square root 8
5.6568542494923801952067548968388Improved Answer:-It is 8
sqrt(18) - sqrt(8) = sqrt(2)
24, because the square root of eight times the square root of eight, is eight. the square root of any number, squared, is the original number. then 8 times 3 is 24
The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.
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.
4 square root of 7
The square root of 8 is 2 times the square root of 2 sqrt(8) = 2 x sqrt(2)
7 for 49 and 8 for 64
That is because 1x1=1 and to be a square root, a number times the same number, it will be a square root of that number*. *Example 8 times the same number (8) will be 64 and 8 will be the square root of 64.
