Answer 1

Resposta:

Explicação passo-a-passo:

A) (36^2 * 50^3) / 20^7 =

1296 * 125000 / 1.280.000.000 =

162.000.000 / 1.280.000.000 =

126,5625

B) (20^-5 ) / (2^-3 - 50^-2) =

1/3200000 / (1/8 - 1/2500) =

1/3200000 / 623/5000 =

1/3200000 * 5000/623 =

5000 / 1.993.600.000 =

2,508025682183 * 10^-6

C) (66^-7 * 70^-28) / 50^-23

(1/5455160701056 * 1/4599865365447399609768010000000000000000000000000000) / 1/1192092895507812500000000000000000000000) =

3814697265625 / 80297615269559200301805562422790459392 =

4,7506980784162 * 10^-26
