Question
Write each of the following in the simplest form:$(a^3)^5 \times a^4$
✓
Answer
$(a^3)^5 \times a^4$
$= (a)^{3\times5} \times a^4 .....($Using $(a^m)^n = a^{mn})$
$= (a)^{15} \times a^4$
$= a^{15 +4} .....($Using $a^m \times a^n = a^{m +n})$
$= a^{19}.$
$= (a)^{3\times5} \times a^4 .....($Using $(a^m)^n = a^{mn})$
$= (a)^{15} \times a^4$
$= a^{15 +4} .....($Using $a^m \times a^n = a^{m +n})$
$= a^{19}.$
