Solve. sqrt of b^4/25=4

Question

A. 2
B. 5*sqrt of 2
C. 3
D. 2*sqrt of 5

Answer 1

Given equation: sqrt(b^4/25) = 4

Applying square root on both sides to eliminate the square root on the left side:

b^4/25 = 4^2
b^4/25 = 16
b^4 = 16 * 25
b^4 = 400

Now, find the fourth root of 400:

b = ±√400
b = ±20

Therefore, the solution to the equation is both 20 and -20.

None of the provided options match the solution to this equation.
