The square root of -9/25 is 0.6i or -0.6i, where i is the imaginary square root of -1.
There are 9 square feet in one square yard. Therefore, 25 square yards is equal to 25 x 9 = 225 square feet.
Assuming the numbers are in metres! 25 × 9 = 225 square metres.
9 + 16 = 25
sqrt(25) - 9 = 5 - 9 = -4sqrt(25 - 9) = sqrt(16) = +4 and -4
9, 16, and 25 are square numbers.
I guess that would be:25 = 9 + 16I guess that would be:25 = 9 + 16I guess that would be:25 = 9 + 16I guess that would be:25 = 9 + 16
9, 16 and 25 are all perfect squares.
sqrt(25/81) = +/- 5/9
A perfect square.
5² = 25 4² = 16 3² = 9 25 - 16 = 9
