Answer:
can you retype the equation
I think it is not correctly typed
How I was taught: Make sure both numbers are a fraction. If not put "1" as the denominator. Multiply straight across. Simplify if you can.
Answer:
-2.
Step-by-step explanation:
(2/9)^4 * (2/9)^-7 = (2/9)^-3 so
(2/9)^-3 = (2/9)^(2m+1)
So -3 = 2m + 1 ( as the base 2/9 is common to both sides of the equation)
2m = -4
m = -2.
25 - 26 is -1. Hope it helped :)
