Question

Find the value of ${13}^8\times [{13}^5÷{13}^{12}]$

• A. ${13}^2$
• B. $13$
• C. ${13}^{-2}$
• D. $\frac{1}{13}$

Answer 1

The correct option is B $13$

${13}^8\times [{13}^5÷{13}^{12}]={13}^8\times \left[{13}^{5-12}\right]$
$={13}^8\times {13}^{-7}$
$={13}^{8-7}={13}^1$
$=13$

So, option $B$ is correct.
