Answer:
7384.46330241 or 7384.5
Step-by-step explanation:
first to find the Y you had to use distributive property
1. 9(1+0.03) = 9+0.27
2. 9+0.27= 9.27
3. 9.27 to the 4th power will be 7384.46330241 or 7384.5
10.13
Remark
The correct way to do this is to add what is inside the brackets (the terms are alike so you can do that) and raise the result to the forth power. Then you multiply by 9.
Solution
1 + 0.03 = 1.03
1.03 ^4 = 1.1255
1.1255 * 9 = 10.13
