Question

(-3^4÷(-2+5)-(-11+5)^3-(-11+3)×(-1)^8-(-162)÷(-5-4)^2

Answer 1

vamos reescrever:
$\frac{ { - 3}^{4} }{( - 2 + 5)} - {( - 11 + 5)}^{3} - ( - 11 + 3) \times {( - 1)}^{8} - \frac{ - 162}{ {( - 5 - 4)}^{2} } \\ \frac{81}{3} - ( - 216) - (11 + 3) - ( \frac{162}{81} ) = \\ 27 + 216 - 8 - 2 = \\ 27 + 216 - 10 = \\ 243 - 10 = 233.$
resposta: 233.
