$745$
To convert a number in scientific notation to a number in standard notation, we must move the decimal point to the left or right by the exponent of $10$ in the scientific notation. If the exponent is positive, we move the decimal right. If the exponent is negative, we move the decimal left. We are trying to convert $7.45\times10^{2}$ to standard notation. Since the exponent of $10$ is $+2$, we move the decimal point $2$ places to the right, giving us $745$.
