Solve 1/2.5*10^7=4*10^-8

$$\frac{ 1 }{ 2.5 \times { 10 }^{ 7 } } =4 \times { 10 }^{ -8 }$$

Verify

Solution Steps

Calculate 10 to the power of 7 and get 10000000.

$$\frac{1}{2.5\times 10000000}=4\times 10^{-8}$$

Multiply 2.5 and 10000000 to get 25000000.

$$\frac{1}{25000000}=4\times 10^{-8}$$

Calculate 10 to the power of -8 and get \frac{1}{100000000}.

$$\frac{1}{25000000}=4\times \frac{1}{100000000}$$

Multiply 4 and \frac{1}{100000000} to get \frac{1}{25000000}.

$$\frac{1}{25000000}=\frac{1}{25000000}$$

Compare \frac{1}{25000000} and \frac{1}{25000000}.

$$\text{true}$$
