$$663 \times { 10 }^{ -34 } \times 3 \times \frac{ { 10 }^{ 8 } }{ 300 \times { 10 }^{ -9 } }$$

I-evaluate

$$\frac{663}{10000000000000000000}=6.63 \cdot 10^{-17}$$

Mga Hakbang ng Solution

Kalkulahin ang 10 sa power ng -34 at kunin ang \frac{1}{10000000000000000000000000000000000}.

$$663\times \frac{1}{10000000000000000000000000000000000}\times 3\times \frac{10^{8}}{300\times 10^{-9}}$$

I-multiply ang 663 at \frac{1}{10000000000000000000000000000000000} para makuha ang \frac{663}{10000000000000000000000000000000000}.

$$\frac{663}{10000000000000000000000000000000000}\times 3\times \frac{10^{8}}{300\times 10^{-9}}$$

I-multiply ang \frac{663}{10000000000000000000000000000000000} at 3 para makuha ang \frac{1989}{10000000000000000000000000000000000}.

$$\frac{1989}{10000000000000000000000000000000000}\times \frac{10^{8}}{300\times 10^{-9}}$$

Para magi-divide ng mga power na may parehong base, i-subtract ang exponent ng denominator mula sa exponent ng numerator.

$$\frac{1989}{10000000000000000000000000000000000}\times \frac{10^{17}}{300}$$

Kalkulahin ang 10 sa power ng 17 at kunin ang 100000000000000000.

$$\frac{1989}{10000000000000000000000000000000000}\times \frac{100000000000000000}{300}$$

Bawasan ang fraction \frac{100000000000000000}{300} sa pinakamabababang term sa pamamagitan ng pag-extract at pag-cancel out sa 100.

$$\frac{1989}{10000000000000000000000000000000000}\times \frac{1000000000000000}{3}$$

I-multiply ang \frac{1989}{10000000000000000000000000000000000} at \frac{1000000000000000}{3} para makuha ang \frac{663}{10000000000000000000}.

$$\frac{663}{10000000000000000000}$$

I-factor

$$\frac{3 \cdot 13 \cdot 17}{2 ^ {19} \cdot 5 ^ {19}} = 6.63 \times 10^{-17}$$
