Answer 1

$\huge\color{cyan}\boxed{\colorbox{black}{ANSWER ❤}}$

${9}^{ \frac{3}{2} } - 3 \times {5}^{0} - {( \frac{1}{81}) }^{ - \frac{ 1}{2} } = 15$

LHS :

${9}^{ \frac{3}{2} } - 3 \times 1 - {( \frac{1}{81}) }^{ - \frac{1}{2} }$

${( {3}^{2}) }^{ \frac{3}{2} } - 3 - {81}^{ \frac{1}{2} }$

${3}^{2 \times \frac{3}{2} } - 3 - \sqrt{81}$

${3}^{3} - 3 - \sqrt{ \times 9 \times 9}$

$27 - 3 - \sqrt{{3}^{2} \times {3}^{2} }$

$24 - (3\times 3)$

$24- 9$

$15$

RHS :

$15$

LHS = RHS
