Question

Which of the following expressions is equivalent to the logarithmic expression log381 + log255?

4 log24 + 3 log216

3
2
log8256 + 4 log2562

2 log48 + log927

log232 + log366

Answer 1

I’m not sure how to read the expression and the answer choices as typed (the subscripts and superscripts got lost). Could you retype using parentheses and underscores for bases, for example:

- log_3(81) + log_5(25)

and each choice like

- 4·log_2(4) + 3·log_2(16)

Once you do that I’ll simplify and pick the matching choice. If you meant a common case (log_3(81)+log_5(25)), note that equals 4+2=6.
