ans is this question 231 ​

Answer 1

231

Step-by-step explanation:

ii)

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

$3 {}^{ 2 \times \frac{5}{2} } - 3.1 - ( \frac{1}{ {9}^{2} } ) {}^{ \frac{ - 1}{2} }$

${3}^{5} - 3 - ( \frac{1 {}^{ \frac{ - 1}{2} } }{ {9}^{2 \times \frac{ - 1}{2} } } )$

${3}^{5} - 3 - ( \frac{1}{9 {}^{ (- 1)} } )$

3^5 - 3 - 9^1

243 - 3 - 9
