Answer
$4.803\times10^{10}$
Work Step by Step
To convert a number from standard notation to scientific notation, we must move the decimal to the left or to the right, counting the number of places, until the number is between $1$ and $10$, and multiply by a power of $10$. If the number is less than $1$, and we moved the decimal to the right, the power of $10$ is the negative number of places we moved the decimal point. If the number is greater than $1$, and we moved the decimal to the left, the power of $10$ is the positive number of places we moved the decimal point.
When trying to convert $48,030,000,000$ to scientific notation, we have to move the decimal point to the left $10$ places. This gives us a coefficient of $4.803$ and a power of $10$ of $10$.
This gives us the expression: $4.803\times10^{10}$
