Question

simplify: (25/16)^4%(225/144)^-3​

Answer 1

$(\frac{25}{16})^{4} \div ( \frac{225}{144})^{ - 3} \\ \\ ( \frac{390625}{65536} ) \div (\frac{144}{225})^{3} \\ \\ \frac{390625}{65536} \div \frac{2985984}{11390625} \\ \\ \frac{390625}{65536} \times \frac{2985984}{11390625} \\ \\ \frac{390625 \times 45.5625}{11390625} \\ \\ \frac{45.5625}{29.16} = 1.5625$
