Question

Resolva as expressões:
A)3²-32+7³
B)(-9+3²)+15
C)12-2⁴+(8,5)²
D)4²+9-2⁵

Answer 1

Resposta:

$a) {3}^{2} - 32 + {7}^{3} \\ = 9 - 32 + 343 \\ = 320$

$b)( - 9 + {3}^{2} ) + 15 \\ = ( - 9 + 9) + 15 \\ = 0 + 15 \\ = 15$

$c)12 - {2}^{4} + (8.5 {)}^{2} \\ = 12 - 16 + 72.25 \\ = - 4 + 72.25 \\ = 68.5$

$d) {4}^{2} + 9 - {2}^{5} \\ = 16 + 9 - 32 \\ = - 23 + 16 \\ = - 7$
