me ajudem por favor ​

Answer 1

Resposta:

a)

$254 \times {10}^{6}$

b)

$8 \times {10}^{4}$

c)

$648 \times {10}^{5}$

d)

$2 \times {10}^{8}$

Explicação passo-a-passo:

a)

$254 \times x = 254000000 < = > \\ < = > x = \frac{254000000}{254} < = > \\ < = > x = 1000000 < = > \\ < = > x = {10}^{6}$

b)

$8 \times x = 80000 < = > \\ < = > x = \frac{80000}{8} < = > \\ < = > x = 10000 < = > \\ < = > x = {10}^{4}$

c)

$648 \times x = 64800000 < = > \\ < = > x = \frac{64800000}{648} < = > \\ < = > x = 100000 < = > \\ < = > x = {10}^{5}$

d)

$2 \times x = 200000000 < = > \\ < = > x = \frac{200000000}{2} < = > \\ < = > x = 100000000 < = > \\ < = > x = {10}^{8}$

Espero que entendas!!
