Answer 2

`10^(12)\left(5\cdot \:10^8\right)\left(3.33\cdot \:10^0\right)`

Exponent rule:
`a^b\cdot \:a^c=a^(b+c)`

`10^(12)\cdot \:10^8\cdot \:10^0=\:10^(12+8+0)`

`5\cdot \:3.33\cdot \:10^(12+8+0)`

Now, add 12 + 8 + 0 =20

`=5\cdot \:3.33\cdot \:10^(20)`

Multiply 5 × 3.33=16.65

`=10^(20)\cdot \:16.65`

Convert to decimal form

`10^(20)=1.0E20`

Multiply

`16.65\cdot \:1.0E20=1.665E21`
