Question

( 3 / 8 )³ + ( 9 / 4)³​

Answer 1

Answer:

You can also do it by the identity a³+b³=(a+b)(a²-ab+b²) but it is very hard to write with fractions with keyboard. So I have done it with direct calculation

Step-by-step explanation:

${( \frac{3}{8} )}^{3} + {( \frac{9}{4} )}^{3}$

$\frac{27}{512} + \frac{729}{64}$

$\frac{27 + 5832}{512}$

$\frac{5859}{512}$

$11.44$
