Question:

Which of the following equations is equivalent to $8894_w57_h16.png$?

A $9639_w76_h38.png$
Explaination

By definition, if $6782_w69_h19.png$ where b > 0 and b ≠ 1, then $9551_w79_h19.png$. Therefore, the given equation $2605_w63_h21.png$ can be rewritten in the form $9238_w88_h19.png$. Then we have $9639_w76_h38.png$.
