Answer:
3) [tex](2x)^{3}[/tex]
Step-by-step explanation:
x = 3
1) [tex]2x^{3}[/tex]
2 x [tex]3^{3}[/tex]
= 54
2) [tex]2x^{3} + 5[/tex]
2 x [tex]3^{3}[/tex] + 5
= 59
3) [tex](2x)^{3}[/tex]
(2 x 3[tex])^{3}[/tex]
[tex]6^{3}[/tex]
=216
4) [tex](x - 1)^{3}[/tex]
(3 - 1[tex])^{2}[/tex]
[tex]2^{3}[/tex]
= 8
