Worked solution

1

1. Multiply the numbers and the powers of 10 separately

(6.2×2.7)×(10−7×10−5)(6.2 \times 2.7) \times (10^{-7} \times 10^{-5})
=16.74×10−12= 16.74 \times 10^{-12}

2. Convert the result to standard form

16.74×10−12=(1.674×101)×10−1216.74 \times 10^{-12} = (1.674 \times 10^1) \times 10^{-12}
=1.674×10−11= 1.674 \times 10^{-11}

Answer

1.674×10−111.674 \times 10^{-11}
