Solve 3.2*10^-7*1.75*10^-2/2.8*10^-9

$$\frac { 3.2 \times 10 ^ { - 7 } \times 1.75 \times 10 ^ { - 2 } } { 2.8 \times 10 ^ { - 9 } }$$

Evaluate

$$2$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -7 and -2 to get -9.

$$\frac{3.2\times 10^{-9}\times 1.75}{2.8\times 10^{-9}}$$

Cancel out 10^{-9} in both numerator and denominator.

$$\frac{1.75\times 3.2}{2.8}$$

Multiply 1.75 and 3.2 to get 5.6.

$$\frac{5.6}{2.8}$$

Expand \frac{5.6}{2.8} by multiplying both numerator and the denominator by 10.

$$\frac{56}{28}$$

Divide 56 by 28 to get 2.

$$2$$

Factor

$$2$$
