Convert 2log3(x) +log3(y²)-log3(y) into single logarithm

Using the logarithmic identity loga(b) + loga(c) = loga(bc), we can simplify the expression as:

2log3(x) + log3(y²) - log3(y)
= log3(x²) + log3(y²) - log3(y)
= log3(x²y²/y)
= log3(x²y)

Therefore, the expression can be simplified into a single logarithm as log3(x²y).
