Solve (2.25*10^-3)*(4*10^5)=

$$(2.25 \times { 10 }^{ -3 } ) \times (4 \times { 10 }^{ 5 } )=$$

Evaluate

$$900$$

Solution Steps

To multiply powers of the same base, add their exponents. Add -3 and 5 to get 2.

$$2.25\times 10^{2}\times 4$$

Calculate 10 to the power of 2 and get 100.

$$2.25\times 100\times 4$$

Multiply 2.25 and 100 to get 225.

$$225\times 4$$

Multiply 225 and 4 to get 900.

$$900$$

Factor

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