Question 688555: I'm having a problem figuring out a problem, I've tried it from a million ways and I know it is super easy. Given the points (5,2) which is on the graph of f(x), find b using the function f%28x%29=log%28b%2Cx%29. (hint, first plug the point in the equation, then solve for b)

Given the points (5,2) which is on the graph of f(x), find b using the function
f%28x%29=log%28b%2Cx%29
:
We know: x = 5; f(x) = 2
:
log%28b%2C5%29 = 2
Write the exponent equiv
b%5E2 = 5
b = sqrt%285%29 + only
