Answer:
25
Step-by-step explanation:
So first we'll input the numbers then since we have them.
5(1) + 3(7) - 1^3
So we're going to use the order of operations here first (PEMDAS) and start with the exponent because the parenthesis I used just represent multiplication. And 1 to the power of anything is still 1. Even 1^1000000000000000000000000000.....
It's still 1.
So now we have this:
5(1) + 3(7) - 1
Now we can multiply:
5 + 21 - 1
Then, add and subtract:
26 - 1
To get:
25
