Solution:
4 log x base 2 - log 5 base 2 = log 125 base 2
log x⁴ base 2 - log 5 base 2 = log 125 base 2
log(x⁴/5) base 2 = log 125 base 2
By Comparing,
=> x⁴/5 = 125
=> x⁴ = 125×5 = 5⁴
=> x = 5 Ans.
4 log x base 2 - log 5 base 2 = log 125 base 2
log x⁴ base 2 - log 5 base 2 = log 125 base 2
log(x⁴/5) base 2 = log 125 base 2
By Comparing,
=> x⁴/5 = 125
=> x⁴ = 125×5 = 5⁴
=> x = 5 Ans.
