Question

calcule:B-9^11:[9^5·(9·9)]​

Answer 1

Explicação passo-a-passo:

Se o 9 for positivo (+) = 6561

$9^{11} :(9^{5}*(9*9))$

$9*9*9*9*9*9*9*9*9*9*9:(9*9*9*9*9*(81))\\31381059609:(59049*81)\\31381059609:4782969\\\\6561$

Se o 9 for negativo (-) = -6561

$-9^{11} :(9^{5}*(9*9))$

$(-9)*(-9)*(-9)*(-9)*(-9)*(-9)*(-9)*(-9)*(-9)*(-9)*(-9):(9*9*9*9*9*(81))\\\\-31381059609:(59049*81)\\\\-31381059609:4782969\\\\\\-6561$
