Question

Using laws of exponents, simplify in the exponential form.
a^3 * a^2 * a^7

Answer 1

$= {a}^{ 3} \times {a}^{2} \times {a}^{7} \\ \\ = {a}^{3 + 2 + 7} \\ \\ = {a}^{12}$

Answer 2

**********************************
We know the exponential law :

x^m × x^n = x^m+n

*********************************
Now ,

a³ × a² × a^7

= a^3+2+7

= a^12
