175, but agree up until then

Turns out that multiplying 25 by 7 is the trickiest part of the question!

$$\frac{{4^8 - 3^8}}{{4^4 + 3^4}}=$$

A. 7
B. 25
C. 156
D. 175
E. 216

$$\frac{{4^8 - 3^8}}{{4^4 + 3^4}}$$ = $$\frac{{(4^4 + 3^4)}*{(4^4 - 3^4)}}{{4^4 + 3^4}}$$

= $$4^4 - 3^4$$
= $$256 - 81$$
= $$175$$

Hence, our answer is option D, 175.
