Solution Steps

To multiply powers of the same base, add their exponents. Add -11 and 24 to get 13.

$$\frac{6.67\times 10^{13}\times 6\times \left(4\times 3000\right)^{-1}}{4\times 3.14\times 3.14}-6.4\times 10^{6}$$

Cancel out 2 in both numerator and denominator.

$$\frac{3\times 6.67\times 10^{13}\times \frac{1}{4\times 3000}}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Multiply 3 and 6.67 to get 20.01.

$$\frac{20.01\times 10^{13}\times \frac{1}{4\times 3000}}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Calculate 10 to the power of 13 and get 10000000000000.

$$\frac{20.01\times 10000000000000\times \frac{1}{4\times 3000}}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Multiply 20.01 and 10000000000000 to get 200100000000000.

$$\frac{200100000000000\times \frac{1}{4\times 3000}}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Multiply 4 and 3000 to get 12000.

$$\frac{200100000000000\times \frac{1}{12000}}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Multiply 200100000000000 and \frac{1}{12000} to get 16675000000.

$$\frac{16675000000}{2\times 3.14\times 3.14}-6.4\times 10^{6}$$

Multiply 2 and 3.14 to get 6.28.

$$\frac{16675000000}{6.28\times 3.14}-6.4\times 10^{6}$$

Multiply 6.28 and 3.14 to get 19.7192.

$$\frac{16675000000}{19.7192}-6.4\times 10^{6}$$

Expand \frac{16675000000}{19.7192} by multiplying both numerator and the denominator by 10000.

$$\frac{166750000000000}{197192}-6.4\times 10^{6}$$

Reduce the fraction \frac{166750000000000}{197192} to lowest terms by extracting and canceling out 8.

$$\frac{20843750000000}{24649}-6.4\times 10^{6}$$

Calculate 10 to the power of 6 and get 1000000.

$$\frac{20843750000000}{24649}-6.4\times 1000000$$

Multiply 6.4 and 1000000 to get 6400000.

$$\frac{20843750000000}{24649}-6400000$$

Subtract 6400000 from \frac{20843750000000}{24649} to get \frac{20685996400000}{24649}.

$$\frac{20685996400000}{24649}$$

Factor

$$\frac{51714991 \cdot 2 ^ {7} \cdot 5 ^ {5}}{157 ^ {2}} = 839222540\frac{11540}{24649} = 839222540.4681731$$
