simplify ((4a)^2)/(4a^9)

Solution

simplify

\frac{( 4 a ) ^{2}}{4 a ^{9}}

Solution

\frac{4}{a ^{7}}

Solution steps

\frac{( 4 a ) ^{2}}{4 a ^{9}}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(4 a)^{2} = 4^{2} a^{2}

= \frac{4 ^{2} a ^{2}}{4 a ^{9}}

\frac{4 ^{2}}{4} = 4

= \frac{4 a ^{2}}{a ^{9}}

Simplify

\frac{a ^{2}}{a ^{9}} : \frac{1}{a ^{7}}

= \frac{4}{a ^{7}}
