Question

5^-6×2^-7×7^6/5^5×4^4×7^-2​

Answer 1

Step-by-step explanation:

$\frac{ {5}^{ - 6} \times {2}^{ - 7} \times {7}^{6} }{ {5}^{5} \times {4}^{4} \times {7}^{ - 2} } \\ \frac{ {5}^{ - 6} \times {5}^{ - 5} \times {2}^{ - 7} \times {7}^{6} \times {7}^{2} }{ {2}^{8} } \\ {5}^{ - 11} \times {2}^{ - 7} \times {2}^{ - 8} \times {7}^{8} \\ {5}^{ - 11} \times {2}^{ - 15} \times {7}^{8}$
