Anyone know how to do this? i’m desperate. exams are coming and i’m in full panic mode. lol

This is pretty easy once you understand how to do it. first, plug in the numbers. for #1, since x,y, and z are all 2, then your equation should look like
2(2)+(-3+2)^2.
then you use order of operations. parenthesis first. -3+2= -1. now your equation should look like
2(2)-1^2. now use exponents.
1×1=1 still, so now the equation is 2(2)+1. 2×2=4, and 4+1=5.

the answer is 5.

now use this info to solve the next one, and good luck!!!

The answer would be c
