2*sqrt(18) - 4*sqrt(2) = 2*sqrt(9*2) - 4*sqrt(2)
= 2*sqrt(9)*sqrt(2) - 4*sqrt(2)
= 2*3*sqrt(2) - 4*sqrt(2)
= 6*sqrt(2) - 4*sqrt(2)
= 2*sqrt(2)

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

Yes and x = 2+square root of 6 or x = 2-square root of 6
[ 2 minus square root of 5 ] is the only one.
sqrt(18) - sqrt(8) = sqrt(2)
Expressed in root form, 5 sqrt(18) - 7 sqrt(8) = sqrt(2)
As 18=2x32, sqrt(18)=sqrt(2x32)=3 sqrt(2) sqrt(18)-sqrt(2)=3 sqrt(2) - sqrt(2) = 2 sqrt(2)

the square root of 18 can be simplified to 3 * the square root of 2.The perfect square 9 is a factor of 18. That means the square root of 9 * the square root of 2 = the square root of 18.the square root of 9 can be simplified to 3.That leaves 3 * the square root of 2.
Oh, what a happy little math problem we have here! When you have 3 times the square root of 2 minus 1 times the square root of 2, you can combine like terms. So, 3 root 2 minus root 2 is equal to 2 times the square root of 2. Just like that, we've created a beautiful, simplified expression.
sqr root of 18 = 3 * square root of 2
x plus the square root of 2
Yes and x = 2+square root of 6 or x = 2-square root of 6
it is 18 because when you put all the numbers back into the square root it becomes the square root of 18 and the square root of 18 squared would be 18
