dont understand this
In the solution it states 2^4-1. Where did the minus 1 come from?
i need my answer in decimals
3/4 divided by 12 is not 9
2-3i/3+2i
underneath the original problem, how do you determine 2 squared (in parenthesis) and how do you determine 5x2x3?
I don't understand how it became 2 to the 4th power
how do I write the answer in an intersection intervals
can you help me on a math problem
need help
