Answer:
[tex]\frac{10}{m^5}[/tex]
Step-by-step explanation:
We have to find the product of [tex](5m^{-2})(2m^{-3})[/tex]
Multiply using the term by term we get
[tex]10m^{-2}m^{-3}[/tex]
Now, using the exponent property [tex]x^a\cdot x^b=x^{1+b}[/tex]
[tex]10m^{-2-3}\\\\=10m^{-5}[/tex]
Finally using the exponent property [tex]x^{-a}=\frac{1}{x^a}[/tex]
[tex]10m^{-5}\\\\\frac{10}{m^5}[/tex]
Third option is correct.
