[tex] \star)2 \times [14 - 2 \times ( {3}^{2} - {2}^{3} )][/tex]

[tex] = 2 \times [14 - 2 \times (9 - 8)][/tex]

[tex] = 2 \times (14 - 2 \times 1)[/tex]

[tex] = 2 \times (14 - 2)[/tex]

[tex] = 2 \times 12[/tex]

[tex] = 24[/tex]

[tex] \star)2 \times (14 - 2) \times {3}^{2} - {2}^{3} [/tex]

[tex] = 2 \times 12 \times 9 - 8[/tex]

[tex] = 24 \times 9 - 8[/tex]

[tex] = 216 - 8[/tex]

[tex] = 208[/tex]

[tex] \star)2 \times 14 - 2 \times ( {3}^{2} - {2}^{3} )[/tex]

[tex] = 28 - 2 \times (9 - 8)[/tex]

[tex] = 28 - 2 \times 1[/tex]

[tex] = 28 - 2[/tex]

[tex] = 26[/tex]
