Answer 2

Answer:

c) 60

Step-by-step explanation:

First we have to cube both the sides.

$( \sqrt[3]{1440} )^{3} = ( \sqrt[3]{3} \times 2 \times \sqrt[3]{x} ) ^{3}$

So now we have

$1440 = 3 \times (2) ^{3} \times x$

hence

$1400 = 3 \times 8 \times x$

therefore

$\frac{1400}{3 \times 8} = x$

and thus we have

$x = 60$
