Question

$125 \times 64 \times m {?}^{2}$
​

Answer 1

Answer:

31

Step-by-step explanation:

(64)⅔ + 3√125+3° + (1/2)^5+(27)-⅔ * (25/9)-½

(4)³*⅔ + (125)⅓ + 1 + (2)^-5 + (3)³*-⅔ * (5/3)²*-½

(4)² + 5 + 1 + 32 + (1/3)²+ 3/5

30 + 1/9 * 3/5

30 + 1/15

465/15

31

Answer 2

$= > {64}^{ \frac{2}{3} } + \sqrt[3]{125} + 3 + ( \frac{1}{2} ) {}^{5} + ( {27})^{ - 23} \times {25}^ \frac{ - 1}{2}$

$= > ({4})^{3} \times \frac{2}{3} + {125}^ \frac{1}{3} + 1 + {2}^{ - 5} + {3}^{3 \times \frac{ - 2}{3} } \times \frac{5}{3} {}^{2} \times \frac{1}{2}$

$= > ( {4})^{2} + 5 + 1 + 32 + \frac{1}{3} {}^{2} + \frac{3}{5}$

$= > 30 + \frac{1}{9} \: \times \frac{3}{5}$

$= > 30 + \frac{1}{15}$

$= > \frac{465}{15}$

$= > 31(required \: answer)$
