2 For questions 15-18, simplify the expression. (15) 15. 13 + 2 + 31 - 40 1 3 커 ooo

Answer 1

We are given the following expression:

`1^3+2^2+3^1-4^0`

The first term is 1 elevated to an exponent. Let's remember that 1 to any exponent is always 12, therefore, we have:

`1^3+2^2+3^1-4^0=1+2^2+3^1-4^0`

Now we solve the second term which is 2 multiply by itself, therefore, we get:

`1+2^2+3^1-4^0=1+4+3^1-4^0`

The third term is 3 elevated to 1. Let's remember that any number elevated to 1 is the same number, therefore, we get:

`1+4+3^1-4^0=1+4+3-4^0`

The fourth term is 4 elevated to zero. Let's remember that any number elevated to zero is 1, therefore, we have:

`1+4+3-4^0=1+4+3-1`

Solving the operations we get:

`1+4+3-1=7`

Therefore, the expression simplifies to 7.
