simply
log9 3 + log 9 27
and
2log7+ log2
To simplify `log9 3 + log9 27`, we can use the logarithmic property that says `loga b + loga c = loga (b * c)`. So we can rewrite the expression as:
`log9 (3 * 27) = log9 81`
Since `9^2 = 81`, we have:
`log9 81 = 2`
Therefore, `log9 3 + log9 27 = 2`.
To simplify `2log7 + log2`, we need more information.
