Answer: 36/a^2b
Step-by-step explanation:
Starting with the question 4a^3b^-2*9a^-5b
Since we have multiplication we multiply our numbers and add exponents
So
4*9=36
and exponents
3+-5=-2
-2+1=-1
So 36a^-2b^-1
BUTTT because we absolutely CANNOT have negative exponents we put them in the denominator to make them positive so our final answer is
[tex]\frac{36}{a^2b}[/tex]
