Solve (2*10^16)+(7*10^16)=?*10^square

$$( 2 \times 10 ^ { 16 } ) + ( 7 \times 10 ^ { 16 } ) = ? \times 10 ^ { \square }$$

Evaluate

$$90000000000000000$$

Solution Steps

Calculate 10 to the power of 16 and get 10000000000000000.

$$2\times 10000000000000000+7\times 10^{16}$$

Multiply 2 and 10000000000000000 to get 20000000000000000.

$$20000000000000000+7\times 10^{16}$$

Calculate 10 to the power of 16 and get 10000000000000000.

$$20000000000000000+7\times 10000000000000000$$

Multiply 7 and 10000000000000000 to get 70000000000000000.

$$20000000000000000+70000000000000000$$

Add 20000000000000000 and 70000000000000000 to get 90000000000000000.

$$90000000000000000$$

Factor

$$2^{16}\times 3^{2}\times 5^{16}$$
