Question
Using laws of exponent, simplify and write the answer in exponential form: $a^4 \times b^4$
✓

Answer

$a^4 \times b^4=a \times a \times a \times a \times b \times b \times b \times b$
$=(a \times b) \times(a \times b) \times(a \times b) \times(a \times b)$
$=(a b) \times(a b) \times(a b) \times(a b)=(a b)^4$
Hence, $a^4 \times b^4=(a b)^4$
