Question

why does 2 log9 turns into 3 log4

Answer 1

sorry i meant turn into 4log 3

Answer 2

wat grade are u in

Answer 3

\(\large a \ log x = log \ x^a\)

\(\large (a \times \ b) \ log \ x = \log \ x^{a \times b} = b \ log \ x^a = a \ log \ x^b\)

so \(\large 2 \ log \ 9 = 2 \ log \ 3^2 = 4 \ log \ 3 \ \ [= log \ 3^4 = log \ 81]\)
