Question

Multiply. state any excluded values.
5/2a . 3/a^2

Answer 1

if this is the problem,
\[ \frac{5}{2a} \cdot \frac{3}{a^2} \]
multiply top times top and bottom times bottom

because dividing by 0 is *very bad*, we do not allow a to be 0

Answer 2

almost, but in the bottom you have
a* a^2

remember that a^2 is short for a*a
so this is a*a*a
can you write this in short form ?

Answer 3

\[ \frac{5}{2a} \cdot \frac{3}{a^2} = \frac{15}{2\cdot a\cdot a \cdot a} \]

Answer 4

we do not want to divide by 0, so we do not want a=0, we say a≠0
that rules out choice c.

the answer is
\[ \frac{15}{2\cdot a\cdot a \cdot a} \]

but you have to rewrite a*a*a in exponent form
a times itself 3 times can be written how ? (other than a*a*a)
