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!!!
