Question

simplify and write in exponential form 2^6*3^2*(-5)^-2/9*5^-4

Answer 1

Answer:

$\frac{ {2}^{6} \times {3}^{2} \times {( - 5)}^{ - 2} }{9 \times ({5})^{ - 4} } \\ = \frac{64 \times 9 \times {5}^{ 4} }{9 \times { - 5}^{ 2} } \\ = \frac{64 \times 9 \times 625}{9 \times 25} \\ = 64 \times 25 \\ = 1600$
