Answer:
-8100
Step-by-step explanation:
(2/5)^-2(-3)^4
Given data
and second term
The first term= (2/5)^-2 and
Second term=(-3)^4
Simplify the first term
(2/5)^-2= 2^-2/ 5^-2= 1/2^2 * 1/5^2
=1/4/ 1/25
=1/4*25/1
=100
Simplify the second term
=(-3)^4
= -81
Hence, 100*81
=-8100

Given:
4 candy bars = 5$
1 candy bar = 5/4
1 candy bar = 1.25$
Now,
5 candy bars = 4$
1 candy bar =4/5
1 candy bar = 0.8$
% change = (0.8-1.25) / 1.25 *100
= 36%
