Starting with the given equation:
sqrt(b^4) / 25 = 4
First, square both sides to get rid of the square root:
b^4 / 25^2 = 4^2
b^4 / 625 = 16
Now, multiply both sides by 625 to get rid of the denominator:
b^4 = 16 * 625
b^4 = 10000
Now take the fourth root of both sides to solve for b:
b = fourth root of 10000
b = 10
So, the correct answer is not listed here. The correct answer is b=10.
