Question

{(1/2)^3 - (1/4)^3} × 2^5​

Answer 1

Answer:

7

Step-by-step explanation:

$= ({ \frac{1}{2} }^{3} - { \frac{1}{4} }^{3} ) \times {2}^{5} \\ = ( \frac{1}{8} - \frac{1}{64} ) \times 64 \\ = ( \frac{8}{64} - \frac{1}{64} ) - 64 \\ = \frac{8 - 1}{64} \times 64 \\ = \frac{7}{64} \times 64 \\ = 7$
