Find the value of the cube root of
four and a half divided by 10 and two-thirds.
Let’s start by converting those
mixed numbers to improper fractions. Recall that dividing by a fraction
is the same as multiplying by its reciprocal. We arrive at the cube root of 27
over 64. This is equivalent to the cube root
of 27 over the cube root of 64. You can use a calculator here, or
remember that three cubed is 27 and four cubed is 64. In any case, the cube root of four
and a half divided by 10 and two-thirds evaluates to three-quarters.
