Question

(3/4)³÷(3/4)-²
iska ans 243/1024 hai but kese pls koi explain karo step by step urgent hai​

Answer 1

Step-by-step explanation:

Using following identities we can solve this question,

${x}^{ - m } = ({ \frac{1}{x} })^{m}$

${x}^{m} \times {x}^{n} = {(x )}^{m + n}$

$(\frac{3}{4})^{3} \div \frac{3}{4} ^{ - 2} \\ (\frac{3}{4})^{3} \div \frac{4}{3}^{2} \\ ( \frac{3}{4})^{3} \times ( \frac{3}{4})^{2} \\ (\frac{3}{4} )^{3 + 2} \\ ( \frac{3}{4} )^{5} \\ \frac{243}{1024}$
