Question

Evaluate 3^-3x5^-2x3^6/25x3^2x5^-5​

Answer 1

Answer:

$\frac{ {3}^{ - 3} \times {5}^{ - 2} \times {3}^{6} }{25 \times {3}^{2} \times {5}^{ - 5} } \\ = \frac{ {3 }^{6} \times {5}^{5} }{ {3}^{3} \times {5}^{2} \times 25 \times {3}^{2} } \\ = \frac{81 \times 9 \times 25 \times 25 \times 5}{27 \times 25 \times 25 \times 9} \\ = \frac{81 \times 5}{27} \\ = 3 \times 5 \\ = 15$
