Question

) 10−21
b) 10−9
c) 1015
d) 103

Answer 1

$\frac{ {10}^{ - 3} \times {(0.001)}^{ - 2} }{ {1000}^{ - 4} }$

$\frac{ {10}^{ - 3} \times( { \frac{1}{1000}) }^{ - 2} }{ {( {10}^{3}) }^{ - 4} }$

$\frac{ {10}^{ - 3} \times {( \frac{1}{ {10}^{3} } )}^{ - 2} }{ {10}^{ - 12} }$

$\frac{ {10}^{ - 3} \times { {(10}^{ - 3}) }^{ - 2} }{ {10}^{ - 12} }$

$\frac{ {10}^{ - 3} \times {10}^{6} }{ {10}^{ - 12} }$

${10}^{ - 3 - ( - 12)} \times {10}^{6}$

${10}^{ - 3 + 12} \times {10}^{6}$

${10}^{9} \times {10}^{6}$

${10}^{9 + 6}$

${10}^{15}$
