Question

Evaluate each of the following
$\begin{array}{cc}& i)5^2\times 5^4\\ & ii)5^8+5^3\\ & iii)(3^2{)}^4\\ & iv){\left(\frac{11}{12}\right)}^2\end{array}$

Answer 1

$\left(i\right)5^2\times 5^4=5^6=15625\left(ii\right)5^8{+5}^3=5^3(1+5^5)=5^3\times 3126=15630\left(iii\right){\left(3^2\right)}^4=3^8=6561\left(iv\right){\left(\frac{11}{12}\right)}^2=\frac{121}{144}$
