Question
Find the L.C.M. of the given expressions
$-9 a^3 b^2, 12 a^2 b^2 c$
$-9 a^3 b^2, 12 a^2 b^2 c$
✓
Answer
$-9 a^3 b^2=-\left(3^2 \times a^3 \times b^2\right)$
$12 a^2 b^2 c=2^2 \times 3 \times a^2 \times b^2 \times c$
$\text { L.C.M. }=-\left(2^2 \times 3^2 \times a^3 \times b^2 \times c\right)$
$=-36 a^3 b^2 c$
$12 a^2 b^2 c=2^2 \times 3 \times a^2 \times b^2 \times c$
$\text { L.C.M. }=-\left(2^2 \times 3^2 \times a^3 \times b^2 \times c\right)$
$=-36 a^3 b^2 c$
