Solve 1/5*10^-2+4*10^3

$$\frac { 1 } { 5 \times 10 ^ { - 2 } } + 4 \times 10 ^ { 3 }$$

Evaluate

$$4020$$

Solution Steps

Calculate 10 to the power of -2 and get \frac{1}{100}.

$$\frac{1}{5\times \frac{1}{100}}+4\times 10^{3}$$

Multiply 5 and \frac{1}{100} to get \frac{1}{20}.

$$\frac{1}{\frac{1}{20}}+4\times 10^{3}$$

Divide 1 by \frac{1}{20} by multiplying 1 by the reciprocal of \frac{1}{20}.

$$1\times 20+4\times 10^{3}$$

Multiply 1 and 20 to get 20.

$$20+4\times 10^{3}$$

Calculate 10 to the power of 3 and get 1000.

$$20+4\times 1000$$

Multiply 4 and 1000 to get 4000.

$$20+4000$$

Add 20 and 4000 to get 4020.

$$4020$$

Factor

$$2^{2}\times 3\times 5\times 67$$
