c) 18

d) 30

e) 44

f) 120

g) -6

h) 450

Explicação passo-a-passo:

a)

$2^{2} + 3 * 2 - 10 =\\4 + 6 - 10=\\10 - 10=\\0$

b)

$3^{2} + 3 * 3 - 10 =\\9 + 9 - 10 =\\18 - 10=\\8$

c)

$4^{2} + 3 * 4 - 10 =\\16 + 12 - 10 =\\28 - 10 =\\18$

d)

$5^{2} + 3 * 5 - 10 =\\25 + 15 - 10 =\\40 - 10 =\\30$

e)

$6^{2} + 3 * 6 - 10 =\\36 + 18 - 10 =\\54 - 10 =\\44$

f)

$10^{2} + 3 * 10 - 10 =\\100 + 30 - 10 =\\130 - 10 =\\120$

g)

$1^{2} + 3 * 1 - 10 =\\1 + 3 - 10 =\\4 - 10 =\\-6$

h)

$20^{2} + 3 * 20 - 10 =\\400 + 60 - 10 =\\460 - 10 =\\450$
