To evaluate this expression, we'll use logarithmic properties:
log₅(y²x⁵ ÷ 125b½)
First, rewrite 125 as 5³:
log₅(y²x⁵ ÷ 5³b½)
Now, apply logarithmic properties:
log₅(y²) + log₅(x⁵) - log₅(5³) - log₅(b½)
Using the power rule:
2log₅(y) + 5log₅(x) - 3 - (1/2)log₅(b)
This is the simplified expression. Without specific values for x, y, and b, we can't further simplify.
