Answer:
Step-by-step explanation:
Let's write the left hand side as a negative power, and 9 as a power of 3:
At this point, for the equality to still stand, the exponents have to be equal:
Where are the choices- lololol
When we have exponents like such (x^-6)^-2 , the numbers are multiplying, so we have x^12, then we take that value and, because it is dividing with the same base, we substract the numbers, so x^12-(-4) = x^16.
Answer:
80
Step-by-step explanation:
because you have to do (11+11)+(9+9)+(10+10) and you would get 22,18,20 and add all together and get 80 because you have to do 22+18=40 then add the remaining 20 and you would get 80
