Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
(5300 + 1335.6) = 5300(1 + 0.07)^n where n is the number of years required
6635.6 = 5300(1.07)^n
(1.07)^n = 1.252
n log 1.07 = log 1.252
n = log 1.252 / log 1.07 = 3.32 years Answer
