log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+log%282%2C%2816%2A16%29%29

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+log%282%2C%2816%5E2%29%29

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+2%2Alog%282%2C%2816%29%29

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+2%2Alog%282%2C%282%5E4%29%29

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+2%2A4%2Alog%282%2C%282%29%29

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+2%2A4%2A1

log%282%2C%2816%29%29+%2B+log%282%2C%2816%29%29+=+8

Relevant log rules used:
log(A) + log(B) = log(A*B)
log(A^B) = B*log(A)
log%28b%2C%28b%29%29+=+1 where b > 0 and b+%3C%3E+1

------------------
log%282%2C16%29+%2B+log%282%2C16%29
16 = 2^4 so log%282%2C16%29+=+4
4 + 4 = 8

which expression are equivalent to the one below? check all that apply log2 16 + log2 16
log2 (16) + log2 (16) = 2 log2 (16) = 2(4) = 8

BTW....I agree with Edwin in that NO expressions are shown!
