Question

Using laws of indices, write proper numbers in the following brackets.

$\text{i.}{3}^5\times 3^2=3^{\left(\right)}$
$\text{ii.}{6}^3÷6^8=6^{\left(\right)}$
$\text{iii.}(4\times 5{)}^2=4^{\left(\right)}\times 5^{\left(\right)}$

Answer 1

$\text{i.}{3}^5\times 3^2=3^{(5+2)}=3^{\left(7\right)}$
$\text{ii.}{6}^3÷6^8=6^{3-8}=6^{-5}$
$\text{iii.}(4\times 5{)}^2=4^{\left(2\right)}\times 5^{\left(2\right)}$
