Question

Simplify 3^-5 * 10^-5 * 125 / 5^-7 * 6^-5​

Answer 1

Answer:

$1.921 \times {10}^{ - 6}$

Step By Step explanation :

$= {3}^{ - 5} \times {10}^{ - 5} \times 125 \div {5}^{ - 7} \times {6}^{ - 5 }$

$= 1 \div {3}^{5} \times 1 \div {10}^{5} \times (125 \times {5}^{7}) \times 1 \div {6}^{5}$

$= 1 \div 243 \times 1 \div 100000 \times 390625 \times 0.00012$

$= 0.0041 \times 0.00001 \times 390625 \times 0.00012$

$= 0.00000192188$

$= 1.921 \times {10}^{ - 6}$
