3*sqrt(45) - 3*sqrt(5) =3*sqrt(9*5) - 3*sqrt(5) = 3*sqrt(9)*sqrt(5) - 3*sqrt(5)
= 3*3*sqrt(5) - 3*sqrt(5) (taking the principal root)
= 9*sqrt(5) - 3*sqrt(5) = 6*sqrt(5)

Square root of 9 is 3... (-7) - 3 = -10 ... Answer: -10
3 times the square root of 5
6
Four of anything minus one of the same thing always leaves three of them.
4 x square root of 10 minus square root of 10 = 3 x square root of 10.
To 3 decimal places, the answer is -3.924
square root(minus 9) = 3 ior in correct mathematical notation it is (+,-)i_square root(9)

Four of anything minus one of the same thing always leaves three of them.
It works out as -26 times the square root of 3
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.
The square root of 45 in simplest form is 3sqrt(5). You take the 2 roots from 45 (5 and 9) and find out the square root of 9 is 3, while the square root of 5 is still just square root 5.
plus or minus. You see it often with square roots. The square root of 9 is plus or minus 3.
