Answer:
5²+1×2 - 4(4) = 11
Step-by-step explanation:
up top when it says a = 4
and b = 5 that's means b and a are those numbers.
then while 4 is touching a that means to multiply. And the 2 up top of b means 5×5, then do order of operations to find the answer. If you dont you'll get it WRONG.
Order of operations is this
Parentheses
Exponents
Multiplication
Division
