Answer 1

$(8 + 1.7) \times {10}^{5} = 9.7 \times {10}^{5} \\ (5 - 1.5) \times {10}^{4} = 3.5 \times {10}^{4} \\ (50+ 6) \times {10}^{2} = 56 \times {10}^{2} \\ (400 + 0.82) \times {10}^{3} = 400.82 \times {10}^{3}$

$5 \times 5 \times {10}^{5 + 7} = 25 \times {10}^{12} \\ 4.2 \times 2 \times {10}^{3 + ( - 7)} = 8.4 \times {10}^{ - 4} \\ 6 \div 3 \times {10}^{5 - 2} = 2 \times {10}^{3} \\ 8 \div 2 \times {10}^{ - 7 - ( - 9)} = 4 \times {10}^{ - 7 + 9} = 4 \times {10}^{2} \\ \\ 3 \div 6 \times {10}^{6 - 15} = \frac{1}{2} \times {10}^{ - 9} = 0.5 \times {10}^{ - 9} = 5 \times {10}^{ - 10}$
