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)
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.
no! the square root of 8 is not retional but the cube root is retional
7.135 * * * * * sqrt(18)*sqrt(8) = sqrt(18*8) = sqrt(144) =12
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

sqrt(18) - sqrt(8) = sqrt(2)
The square root of minus 8 is equal to the square root of 8 times the square root of minus 1, or 2.8284i.
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
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
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.
Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)
