8​

Answer 1

Step-by-step explanation:

$\frac{ {6 }^{2} \times {b}^{ - 4} \times {2}^{ - 3} }{ {6}^{ - 3} \times 12 \times {b}^{ - 8} } \\ = {6}^{(2 + 3)} \times {b}^{ (- 4 + 8)} \div {2}^{3} \times 12 \\ {6}^{5} \times {b}^{4} \div 96 \\ \frac{7776 \times {b}^{4} }{96} \\ 81 \times {b}^{4} \\ {9}^{2} \times {b}^{4}$
