Solve 3.2*10^-19*1.2*0.4

$$3.2 \times { 10 }^{ -19 } \times 1.2 \times 0.4$$

Evaluate

$$0.0000000000000000001536$$

Solution Steps

Calculate 10 to the power of -19 and get \frac{1}{10000000000000000000}.

$$3.2\times \frac{1}{10000000000000000000}\times 1.2\times 0.4$$

Multiply 3.2 and \frac{1}{10000000000000000000} to get \frac{1}{3125000000000000000}.

$$\frac{1}{3125000000000000000}\times 1.2\times 0.4$$

Multiply \frac{1}{3125000000000000000} and 1.2 to get \frac{3}{7812500000000000000}.

$$\frac{3}{7812500000000000000}\times 0.4$$

Multiply \frac{3}{7812500000000000000} and 0.4 to get \frac{3}{19531250000000000000}.

$$\frac{3}{19531250000000000000}$$

Factor

$$\frac{3}{2 ^ {13} \cdot 5 ^ {22}} = 1.536 \times 10^{-19}$$
