Question

{(1/2)^-3 + (1/3)^-2}^-1 ÷ (1/4)^-1​

Answer 1

Answer:

${( \frac{2}{1}) }^{3} + {( \frac{1}{3}) }^{( - 2) \times ( - 1)} \div {( \frac{4}{1}) }^{1} \\ = \frac{ 8 }{1} + {( \frac{1}{3}) }^{2} \times {( \frac{1}{4}) }^{1} \\ = 8 + \frac{1}{9 } \times \frac{1}{4} \\ = 8 + \frac{1}{36} \\ = 8 \frac{1}{36}$
