Sagot :

In order to evaluate the value of each expression, let's use the values of x, y and z given in each one.

a.

[tex]\begin{gathered} 7x^2-z \\ =7\cdot1^2-3 \\ =7-3 \\ =4 \end{gathered}[/tex]

b.

[tex]\begin{gathered} (x+4)^3-y \\ =(1+4)^3-2 \\ =5^3-2 \\ =125-2 \\ =123 \end{gathered}[/tex]

c.

[tex]\begin{gathered} y(x+3^3) \\ =2(1+9) \\ =2\cdot10 \\ =20 \end{gathered}[/tex]

d.

[tex]\begin{gathered} (7-y+z)^2 \\ =(7-2+3)^2 \\ =8^2 \\ =64 \end{gathered}[/tex]

e.

[tex]\begin{gathered} 0.241x+x^3 \\ =0.241\cdot1+1^3 \\ =1.241 \end{gathered}[/tex]
