Variables and Algebraic Expressions: Using powers

$\frac{9m}{3m^2}\times\frac{3m}{6}=$

According to the laws of multiplication, we must first simplify everything into one exercise:

$\frac{9m\times3m}{3m^2\times6}=$

We will simplify and get:

$\frac{9m^2}{m^2\times6}=$

We will simplify and get:

$\frac{9}{6}=$

We will factor the expression into a multiplication:

$\frac{3\times3}{3\times2}=$

We will simplify and get:

$\frac{3}{2}=1.5$

$0.5m$

$\frac{8x^2}{4x}+3x=$

$5x$
