Question

Mano tô preso nisso aqui

b)(3^ 9 *3^ -6 *3^ 5 ):(2^ 3 *3^ 3 *2^ -2 *3) /(-3^ -2 )^ -2 +(2^ -2 .2^ 4 )^ 2

Answer 1

Resposta:

Explicação passo a passo:

$\frac{\left(3^9\cdot 3^{-6}\:\cdot 3^{\:5}\:\right):\left(2^{3\:}\:\cdot 3^{3\:}\:\cdot 2^{-2\:}\:\cdot 3\right)}{\left(-3^{\:-2}\:\right)^{-2\:}\:+\left(2^{-2\:}\:\cdot 2^{4\:}\right)^2}\\\\\frac{3^{8}:(2\cdot 81) }{3^{4}+2^{4} } \\\\\frac{3^{8}:162}{81+16} \\\\\frac{3^8}{\frac{162}{96}}=\frac{6561}{15714} =\frac{81}{194}$
