Các bước tìm nghiệm

Để nhân các lũy thừa của cùng một một cơ số, hãy cộng số mũ của chúng. Cộng -31 với -9 để có kết quả -40.

$$\frac{3^{2}\times \left(6\times 626\times 10^{-34}\right)^{2}}{8\times 9\times 1\times 10^{-40}\times 4805}$$

Tính 3 mũ 2 và ta có 9.

$$\frac{9\times \left(6\times 626\times 10^{-34}\right)^{2}}{8\times 9\times 1\times 10^{-40}\times 4805}$$

Nhân 6 với 626 để có được 3756.

$$\frac{9\times \left(3756\times 10^{-34}\right)^{2}}{8\times 9\times 1\times 10^{-40}\times 4805}$$

Tính 10 mũ -34 và ta có \frac{1}{10000000000000000000000000000000000}.
