$$0.8 \div (0.25 \times { 10 }^{ -3 } \times 1.6 \times { 10 }^{ -19 } )$$

I-evaluate

$$20000000000000000000000$$

Mga Hakbang ng Solution

Para mag-multiply ng mga power na may parehong base, i-add ang mga exponent ng mga ito. I-add ang -3 at -19 para makuha ang -22.

$$\frac{0.8}{0.25\times 10^{-22}\times 1.6}$$

Kalkulahin ang 10 sa power ng -22 at kunin ang \frac{1}{10000000000000000000000}.

$$\frac{0.8}{0.25\times \frac{1}{10000000000000000000000}\times 1.6}$$

I-multiply ang 0.25 at \frac{1}{10000000000000000000000} para makuha ang \frac{1}{40000000000000000000000}.

$$\frac{0.8}{\frac{1}{40000000000000000000000}\times 1.6}$$

I-multiply ang \frac{1}{40000000000000000000000} at 1.6 para makuha ang \frac{1}{25000000000000000000000}.

$$\frac{0.8}{\frac{1}{25000000000000000000000}}$$

I-divide ang 0.8 gamit ang \frac{1}{25000000000000000000000} sa pamamagitan ng pagmu-multiply sa 0.8 gamit ang reciprocal ng \frac{1}{25000000000000000000000}.

$$0.8\times 25000000000000000000000$$

I-multiply ang 0.8 at 25000000000000000000000 para makuha ang 20000000000000000000000.

$$20000000000000000000000$$

I-factor

$$2^{23}\times 5^{22}$$
