$2.358\times10^6$

#### 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. We are trying to convert $2,358,000$ to scientific notation. We move the decimal $6$ places to the left, giving us $2.358$ as the coefficient, and $6$ as the power of $10$. This gives us $2.358\times10^6$
