To find the value of b for b to the 2nd power = 36/64, we need to simplify the right side of the equation first. 36/64 can be reduced to 9/16 by dividing both numbers by 4. Now, we have b^2 = 9/16. To find the value of b, we need to take the square root of both sides. The square root of 9/16 is 3/4. Therefore, the value of b is 3/4.
So the final answer is 3/4
