40

Solution steps

20 \div \frac{1}{2}

Convert element to fraction:

20 = \frac{20}{1}

= \frac{20}{1} \div \frac{1}{2}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{20}{1} \times \frac{2}{1}

Apply rule

\frac{a}{1} = a

= 20 \times 2

Multiply the numbers:

20 \times 2 = 40

= 40

(\frac{- 4 ^{3}}{- 2 ^{3}})^{2}

24 x^{3} y

\frac{4 x ^{3} + x + 1}{2 x ^{2} - x + 1}

49 x^{4} - 4 y^{2}

\frac{( x + y ) ^{3} - x ^{3}}{y}
