B)

$5.7 \times 10 {}^{4}$

C)

$6.9 \times 10 {}^{5}$

D)

$</strong><strong>0</strong><strong>,</strong><strong>4</strong><strong>.</strong><strong>{</strong><strong>1</strong><strong>0</strong><strong>}</strong><strong>^</strong><strong>{</strong><strong>2</strong><strong>}</strong><strong>$

Explicação passo-a-passo:

A)

$8.2 \times 10 {}^{2} \times 4 \times 10 {}^{3} \\ 8.2 \times 100 \times 4 \times 1000 \\ 820 \times 41000 \\ 3362000 \\ 33.62 \times 10 {}^{5}$

B)

$5.1 \times 10 {}^{4} + 6 \times {10}^{3} \\ 5.1 \times 10000 + 6 \times 1000 \\ 51.000 + 6.000 \\ 57.000 \\ 5.7 \times {10}^{4}$

C)

$7.3 \times 100000 - 40 \times 1000 \\ 730000 - 40000 \\ 690000 \\ 6.9 \times {10}^{5}$

D)

$2.8 \times 100000 \div 7 \times -1000 \\ 280000 \div -7000 \\ -40 \\ -0,4.{10}^{2}$
