Question

The simplified form of (5 POWER-1 * 2 POWER-2) / 4 POWER-1

Answer 1

Answer:

$= > given \\ = > \frac{ {5}^{ - 1} \times {2}^{ - 2} }{ {4}^{ - 1} } \\ using \: the \: formula \: {a}^{ - n} = \frac{1}{ {a}^{n} } \\ > > {5}^{ - 1} = \frac{1}{5} \\ > > {2}^{ - 2} = \frac{1}{ {2}^{2} } \\ > > {4}^{ - 1} = \frac{1}{4} \\ now \: substitute \: those \: values \\ \: in \: the \: given \: equation \\ \frac{ \frac{1}{5} \times \frac{2}{ {2}^{2} } }{ \frac{1}{4} } \\ \frac{1}{5} \times \frac{2}{ {2}^{2} } \times \frac{4}{1} \\ \frac{1}{5} \times \frac{2}{4} \times \frac{4}{1} \\ = \frac{2}{5}$
