Question

Help how can I match these for a better grade

Answer 1

The first expression is:

`\begin{gathered} 4+8((1)/(4)+2) \\ =4+8((9)/(4)) \\ =4+18 \\ =22 \end{gathered}`

Therefore, the first expression matches to 22

The second expression is:

`\begin{gathered} 0.25\cdot4^3-1 \\ =(1)/(4)\cdot4^3-1 \\ =4^2-1 \\ =16-1 \\ =15 \end{gathered}`

Therefore, the second expression matches to 15

The third expression is:

`\begin{gathered} 1+5\cdot2+(1+3)^2 \\ =1+10+4^2 \\ =1+10+16 \\ =27 \end{gathered}`

Therefore, the third expression matches to 27
