Square root of 45 times square root of 45 = 45
45 is the square root of 2,025 (45 x 45 = 2025).
√45 = 6.708203932499369
the answer is 4.5
x2 = 45take square root of both sidesx = positive and negative square root of 45x = + and - 3√(5)Improved Answer:-9 and 36 are square numbers and they add up to 45
45+45+90
It is 2*sqrt(5).
No, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.
Square root of 45 times square root of 45 = 45
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
45 is the square root of 2,025 (45 x 45 = 2025).
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.
3 times the square root of 5
