Question

what is 2^-3 times by 4^-1


what is 10^-2 times by 2^-4

Answer 1

${2}^{ - 3} \times {4}^{ - 1} \\ \\ = \frac{1}{ {2}^{3} \times {4}^{1} } \\ \\ = \frac{1}{32} = {2}^{ - 5}$

${10}^{ - 2} \times {2}^{ - 4} \\ \\ = \frac{1}{ {10}^{2} \times {2}^{4} } \\ \\ = \frac{1}{100 \times 16} \\ \\ = \frac{1}{1600} = {40}^{ - 2}$
