Question 94340: ``Hi, I need help with the problem:
3+ (1 + 2^3)^2
I keep getting different answers. When I worked it I got 68, but when I used my calculator it said 84. When I worked it, I squared the 1 and got 1 and squared the 2^3 and got 2^6. Then I added 1 to the 64 (2^6) and got 65. Then I added 3 and got 68. I know how the caluclator got 84, but the way I learned it you are supposed to multiple by the 2 first. If you could help me that would be great.
Thanks

3+ (1 + 2^3)^2
= 3 + (1+8)^2
= 3 + 9^2
= 84
