Question

Write the proper numbers in the boxes.

(5) ${\left(5.7\right)}^4\times {\left(5.7\right)}^2={\left(5.7\right)}^{\boxed{}}$

Answer 1

${\left(5.7\right)}^4\times {\left(5.7\right)}^2={\left(5.7\right)}^{\boxed{}}$
Consider (5.7)⁴ × (5.7)²
= (5.7)⁴⁺² (a^m × aⁿ = a^m+n)
$={\left(5.7\right)}^{\boxed{6}}$
