Well, if you were to work it it it would be A(3).
You usually do not combine the terms as in letter C(9^90).
I would go with letter A.😀
Simplify the expression
(3)^10 (3)^-9
A; 3
B; 1/3
C;9^-90 (my answer)
D 9
Am i correct?

Sorry first line is supposed to be: Well if you were to work it out, it would...
Oh yeah that makes sense. Thanks for the help!!!
umm...how do you get that answer as three though? mabye i can use that same method in the future
You keep the base and add the exponents.
base is 3 and exponents add to 1 so 3^1= 3
base is 3 and exponents add to 1 so 3^1= 3
9^-90 would be (3*3)^(10 * -9)
Better review the properties of exponents some more.
