Question

Evaluate each expression using the values given.1) n ^2 − m; use m = 7, and n = 8 2) 8(x − y); use x = 5, and y = 2 3) yx ÷ 2; use x = 7, and y = 2 4) m − n ÷ 4; use m = 5, and n = 8 5) x − y + 6; use x = 6, and y = 1 6) z + x^3 ; use x = 1, and z = 19 7) q ÷ 6 + p; use p = 10, and q = 12 8) 15 − (m + p); use m = 3, and p = 10 9) y [x − (9 − 4y)]; use x = 4, and y = 2 10) x – [x − (x – y^3 )]; use x = 9, and y = 1

Answer 1

`\begin{gathered} 1\Rightarrow n^2-m=8^2-7=57 \\ 2\Rightarrow8(x-y) \\ 8(5-2)=24 \\ 3\Rightarrow(yx)/(2)=(2*7)/(2)=7 \\ 4\Rightarrow(m-n)/(4)=(5-8)/(4)=-(3)/(4) \\ 5\Rightarrow x-y+6=6-1+6=11 \end{gathered}`
