Solve 6.67*10^-11*200000*400000)div4000^2

$$6.67 \times { 10 }^{ -11 } \times 200000 \times 400000) \div { 4000 }^{ 2 }$$

Evaluate

$$5.336$$

Solution Steps

Calculate 10 to the power of -11 and get \frac{1}{100000000000}.

$$6.67\times \frac{1}{100000000000}\times 200000\times 400000$$

Multiply 6.67 and \frac{1}{100000000000} to get \frac{667}{10000000000000}.

$$\frac{667}{10000000000000}\times 200000\times 400000$$

Multiply \frac{667}{10000000000000} and 200000 to get \frac{667}{50000000}.

$$\frac{667}{50000000}\times 400000$$

Multiply \frac{667}{50000000} and 400000 to get \frac{667}{125}.

$$\frac{667}{125}$$

Factor

$$\frac{23 \cdot 29}{5 ^ {3}} = 5\frac{42}{125} = 5.336$$
