Question

2x+y to the Power 2-xy for x =1 and y=4?

Answer 1

So we plug in x=1 & y=4 to solve 2x + y2 - xy
2×1 + 42 - 1×4 , Follow order of operations: PEMDAS
2×1 + 16 - 1×4 , because Exponents first, and 42 = 4×4 = 16
2 + 16 - 4 , because next, we can take care of all the Multiplication
18 - 4 , then Addition
14 , then Subtraction

Answer 2

`\begin{gathered} 2x+y^2-xy \\ \text{Here, x=1, y=4} \\ \text{Substitute all the values in the above equation.} \\ =2*1+4^2-1*4 \\ =2+16-4 \\ =14 \end{gathered}`
