Answer

$7.6\times10^{7}$

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 $76,000,000$ to scientific notation, we have to move the decimal point to the left $7$ places. This gives us a coefficient of $7.6$, and our power of $10$ will be $7$. This gives us the expression: $7.6\times10^{7}$
