Answer 1

$8620000 = 8.62 \times 10 {}^{6} \\ 96300 = 9.63 \times {10}^{4} \\ 0.000312 = 3.12 \times 10 {}^{ - 4} \\ 0.000046 = 4.6 \times 10 {}^{ - 5} \\ 10 {}^{ - 7} \times 10 {}^{ - 4} = 10 {}^{ - 7 + ( - 4)} = 10 {}^{ - 7 - 4} = 10 {}^{ - 11} \\ 10 {}^{6} \times 10 {}^{ - 2} = 10 {}^{6 + ( - 2)} = 10 {}^{6 - 2} = 10 {}^{4} \\ 10 {}^{ - 13} \div 10 {}^{ - 3} = 10 {}^{ - 13 - ( - 3)} = 10 {}^{ - 13 + 3} = 10 {}^{ - 10} \\ 10 {}^{ - 15} \div 10 {}^{5} = 10 {}^{ - 15 - 5} = 10 {}^{ - 20}$
