Question

Using laws of exponents , simplify and write the answer in exponential form:

$a^5\times a^7$

Answer 1

Given,

$$\begin{gathered} a^5\times a^7 \\ ={\left(a\right)}^{5+7} \\ ={\left(a\right)}^{12} \end{gathered}$$ [ Using exponent law : $a^m\times a^n=a^{m+n}$ ]

Hence, required value is ${\left(a\right)}^{12}$ .
