AcademicMathematicsNCERTClass 8

Given:

\( \left(\frac{2}{5} a^{2} b\right) \times\left(-15 b^{2} a c\right) \times\left(\frac{-1}{2}\right) c^{2} \)

To do:

We have to evaluate the given expression.

Solution:

$(\frac{2}{5} a^{2} b) \times(-15 b^{2} a c) \times(\frac{-1}{2}) c^{2}=\frac{2}{5} \times(-15) \times(\frac{-1}{2}) \times a^{2} \times a \times b \times b^{2} \times c \times c^{2}$

$=3 \times a^{2+1} \times b^{1+2} \times c^{1+2}$

$=3 a^{3} b^{3} c^{3}$
