Solution

simplify

\frac{3 \cdot ( - 4 ^{2} )}{8 + 12}

Solution

- \frac{12}{5}

+1

Solution steps

\frac{3 ( - 4 ^{2} )}{8 + 12}

Apply rule:

a (- b) = - ab

3 (- 4^{2}) = - 3 \cdot 4^{2}

= \frac{- 3 \cdot 4 ^{2}}{8 + 12}

Add the numbers:

8 + 12 = 20

= \frac{- 3 \cdot 4 ^{2}}{20}

Factor the number:

20 = 4 \cdot 5

= \frac{- 3 \cdot 4 ^{2}}{4 \cdot 5}

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

= \frac{- 3 \cdot 4}{5}

\frac{- 3 \cdot 4}{5} = - \frac{12}{5}

= - \frac{12}{5}
