Solve =40*10^-4*2*10^11*12*10^-4

$$= 40 \times 10 ^ { - 4 } \times 2 \times 10 ^ { 11 } \times 12 \times 10 ^ { - 4 }$$

Evaluate

$$960000$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -4 and 11 to get 7.

$$40\times 10^{7}\times 2\times 12\times 10^{-4}$$

To multiply powers of the same base, add their exponents. Add 7 and -4 to get 3.

$$40\times 10^{3}\times 2\times 12$$

Calculate 10 to the power of 3 and get 1000.

$$40\times 1000\times 2\times 12$$

Multiply 40 and 1000 to get 40000.

$$40000\times 2\times 12$$

Multiply 40000 and 2 to get 80000.

$$80000\times 12$$

Multiply 80000 and 12 to get 960000.

$$960000$$

Factor

$$2^{9}\times 3\times 5^{4}$$
