Solve 9*10^9*0.7*10^-6*0.8*10

$$9 \times 10 ^ { 9 } \times 0.7 \times 10 ^ { - 6 } \times 0.8 \times 10$$

Evaluate

$$50400$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 9 and -6 to get 3.

$$9\times 10^{3}\times 0.7\times 0.8\times 10$$

To multiply powers of the same base, add their exponents. Add 3 and 1 to get 4.

$$9\times 10^{4}\times 0.7\times 0.8$$

Calculate 10 to the power of 4 and get 10000.

$$9\times 10000\times 0.7\times 0.8$$

Multiply 9 and 10000 to get 90000.

$$90000\times 0.7\times 0.8$$

Multiply 90000 and 0.7 to get 63000.

$$63000\times 0.8$$

Multiply 63000 and 0.8 to get 50400.

$$50400$$

Factor

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