Question

a=(3³×81²×3×3³):3¹⁵ ​

Answer 1

$a = ( {3 }^{3} \times {81}^{2} \times 3 \times {3}^{3} ) \div {3}^{15}$

$a = [{3 }^{3} \times ( { {3}^{4} })^{2} \times 3 \times {3}^{3} ]\div {3}^{15}$

$a = ({3 }^{3} \times { 3 }^{4 \times 2} \times 3 \times {3}^{3} )\div {3}^{15}$

$a = ({3 }^{3} \times { 3 }^{8} \times 3 \times {3}^{3} )\div {3}^{15}$

$a = ({3 }^{3 + 8 + 1 + 3} )\div {3}^{15}$

$a = {3}^{15} \div {3}^{15}$

$a = {3}^{15 - 15}$

$a = {3}^{0} = 1$
