Explanation:
Given
Digit: 1,500,000
Required
Represent using scientific notation
We start by expressing the given digit as a product of 1.5 and a multiple of 10
1,000,000 can be represented as 10⁶
So; the digit becomes
Hence, the scientific notation of 1,500,000 is 1.5 * 10⁶

Explanation:
That would be like having a larger output that an input.
Not only are you getting something for nothing, you are getting more than something for nothing.
Our planet just does not work that way. There is one thought experiment that you could perform for yourself that would show you why this isn't possible. It's called Maxwell's Demon.
Pretend that you are in a room that is divided by a wall that does not absorb heat. Pretend also that there is a window in the wall and there is a demon who operates the window.
The demon is programmed so that he opens the window only for the fastest moving molecules. That means that one room would loose heat, and the other would increase its heat content. Your getting something for nothing. You could live in the artificially heated room without spending a dime on heating bills (Of course you might have to feed the demon something). That thought experiment was developed just as it became understood that temperature is the measurement of a mixture of faster and slower moving molecules.
