Solve (3*10^5)*(3*10^5)

$$(3 \times { 10 }^{ 5 } ) \times (3 \times { 10 }^{ 5 } )$$

Evaluate

$$90000000000$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 5 and 5 to get 10.

$$3\times 10^{10}\times 3$$

Calculate 10 to the power of 10 and get 10000000000.

$$3\times 10000000000\times 3$$

Multiply 3 and 10000000000 to get 30000000000.

$$30000000000\times 3$$

Multiply 30000000000 and 3 to get 90000000000.

$$90000000000$$

Factor

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