Question

resolva 1¹ + (-1¹) + 2² + (-2²) + 3³ + (-3³)​

Answer 1

Olá!

${2}^{2} = 2 \times 2 = 4$

${( - 2) }^{2} = - 2 \times - 2 = + 4 = 4$

${3}^{3} = - 3 \times - 3 \times - 3 = - 27$

${( - 3)}^{3} = - 3 \times - 3 \times - 3 = - 27$

$1 + {2}^{2} + {( - 2)}^{2} + {3}^{3} + {( - 3)}^{3} =$

$= 1 + 4 + 4 + 27 - 27$

$= 1 + 4 + 4 + 0$

$= 9$
