Solve 1.5*10^6/2.5*10^-4*7

$$\frac { 1.5 \times 10 ^ { 6 } } { 2.5 \times 10 ^ { - 4 } } \cdot 7$$

Evaluate

$$42000000000$$

Solution Steps

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{1.5\times 10^{10}}{2.5}\times 7$$

Calculate 10 to the power of 10 and get 10000000000.

$$\frac{1.5\times 10000000000}{2.5}\times 7$$

Multiply 1.5 and 10000000000 to get 15000000000.

$$\frac{15000000000}{2.5}\times 7$$

Expand \frac{15000000000}{2.5} by multiplying both numerator and the denominator by 10.

$$\frac{150000000000}{25}\times 7$$

Divide 150000000000 by 25 to get 6000000000.

$$6000000000\times 7$$

Multiply 6000000000 and 7 to get 42000000000.

$$42000000000$$

Factor

$$3\times 7\times 2^{10}\times 5^{9}$$
