Koraci rješenja

Da biste podijelili potencije s istom bazom, oduzmite eksponent brojnika od eksponenta nazivnika.

$$\frac{138\times 2715}{101\pi \sqrt{2}\times 10^{28}\times \left(35\times 10^{-10}\right)^{2}}$$

Pomnožite 138 i 2715 da biste dobili 374670.

$$\frac{374670}{101\pi \sqrt{2}\times 10^{28}\times \left(35\times 10^{-10}\right)^{2}}$$

Izračunajte koliko je 28 na 10 da biste dobili 10000000000000000000000000000.

$$\frac{374670}{101\pi \sqrt{2}\times 10000000000000000000000000000\times \left(35\times 10^{-10}\right)^{2}}$$

Pomnožite 101 i 10000000000000000000000000000 da biste dobili 1010000000000000000000000000000.

$$\frac{374670}{1010000000000000000000000000000\pi \sqrt{2}\times \left(35\times 10^{-10}\right)^{2}}$$

$$\frac{374670}{1010000000000000000000000000000\pi \sqrt{2}\times \left(35\times \frac{1}{10000000000}\right)^{2}}$$

Pomnožite 35 i \frac{1}{10000000000} da biste dobili \frac{7}{2000000000}.

$$\frac{374670}{1010000000000000000000000000000\pi \sqrt{2}\times \left(\frac{7}{2000000000}\right)^{2}}$$

Izračunajte koliko je 2 na \frac{7}{2000000000} da biste dobili \frac{49}{4000000000000000000}.

$$\frac{374670}{1010000000000000000000000000000\pi \sqrt{2}\times \frac{49}{4000000000000000000}}$$

Pomnožite 1010000000000000000000000000000 i \frac{49}{4000000000000000000} da biste dobili 12372500000000.

$$\frac{374670}{12372500000000\pi \sqrt{2}}$$

Racionalizirajte nazivnik \frac{374670}{12372500000000\pi \sqrt{2}} množenje brojnik i nazivnik \sqrt{2}.

$$\frac{374670\sqrt{2}}{12372500000000\pi \left(\sqrt{2}\right)^{2}}$$

Kvadrat od \sqrt{2} je 2.

$$\frac{374670\sqrt{2}}{12372500000000\pi \times 2}$$

Skratite 10 u brojniku i nazivniku.

$$\frac{37467\sqrt{2}}{2\times 1237250000000\pi }$$

Pomnožite 2 i 1237250000000 da biste dobili 2474500000000.
