asked 02/18/19Log5(x2) = 1 + Log5(6)
There is nothing online about “1 + logarithms” and when there is they expotentate. Why is this rule used? Everything is easy except for when it is explained as “log5(51+log5(6))” which somehow equals 30

note that log5(5) = 1 so
log5(x^2) = log5(5) + log5(6)
5^log5(x^2) = 5^log5(5) * 5^log5(6)
x^2 = 30
x = sqrt(30)
