evaluate: (log5 20^4)(log20 5^4) I don't get it

Solve for x: log5(x-2)+ log5 (x-4) = log6(x-1)

log5 4 log5 - 2x = log31

log5(15)+log5(405)−5log5(3) =?

Log5(3÷5)+3log5(15÷2)-log5(81÷8)

Evaluate Log4^5-log5^4/log 4^1/5+log 5^1/4

log5 +log20 log√8 ÷ log8

Evaluate 3log2+log20-log16

Evaluate log5 8 + log5 10 - 2 log5 20

2Log5 2/5+log5√9-log5 72/125+log5√10

f(x)=log5 x Evaluate f (1/25)
