sqrt(45) = sqrt(9 x 5) = 3 sqrt(5)
one over the square root of 2 or 0.850903525
First you have to set up a proprtion. 45 over x equals x over 5. Then you get x squared equals 225(45*5). Finally you have to find the square root of 225 which is 15.
1/square root 2
5 square root of 2 units
The length of either leg is the square root of 60.5, or about 7.8 (either leg has a length equal to the square root of 121/2).This can also be found by formula to be c/sqrt 2 or 11/[sqrt 2].7.78
45+45+90
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.
45 is 9 times 5, and 9 is 3 squared, so the answer is 9 times the square root of 5.
sqrt(20*9) = sqrt(2*2*5*9) =2*sqrt(45)
You probably mean what is the simplest form of sqrt 45....? 45=3x3x5 3x3 is a square number, so sqrt45=sqrt(9*5)=sqrt(9)*sqrt(5)=3*sqrt(5) * indicates multiplication sqrt indicates a square root (also known as a surd (in the english national curriculum) or a radical...apparently
3√5
5sqrt(405) = 5sqrt(815) = 5sqrt(81)sqrt(5) = 59sqrt(5) = 45sqrt(5)
45= 9 x 5. Since we are dealing with square roots, you would be able to square the 9 in the equation: 9 squared x 5 squared = 3 x 5 squared or 3 V5 (V is the squareing sign)
Square root of 45 times square root of 45 = 45
The square root of 45 is approximately 6.71, and the square root of 67 is approximately 8.19. Therefore, the square root of 45 minus the square root of 67 is approximately 6.71 - 8.19, which equals about -1.48.
45 is the square root of 2,025 (45 x 45 = 2025).
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.
