b) [15×(17-16)×2-5×3]×4-10

=(15×1×2-15)×4-10

=(15×2-15)×4-10

=(30-15)×4-10

=15×4-10

=60-10

=50

c)

[tex] {5}^{3}-{3}^{2} + {7}^{2} + {11}^{2} = 125 - 9 + 49 + 121 = 116 + 49 + 121 = 165 + 121 = 286[/tex]

d)

[tex] {4}^{3} - {5}^{2} + {13}^{0} - {14}^{1} = 64 - 25 + 0 - 1 = 39 + 0 - 1 = 39 - 1 = 38[/tex]
