\huge\text{Hey there!}


\mathsf{(7* 10^5) + (4 * 10^2)}\\\mathsf{= 7* 10^5 + 4 * 10^2}


\large\textsf{Let's solve for the LEFT SIDE first}


\mathsf{7* 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10*10*10*10*10}\\\mathsf{= 100 * 100* 10}\\\mathsf{= 10,000 * 10}\\\mathsf{= 100,000}\\\\\mathsf{7*100,000}\\\mathsf{= 700,000}


\large\textsf{NEW EQUATION: }\bold{700,000} + {4}* 10^2


\large\textsf{Now, let's solve for the RIGHT SIDE last}


\mathsf{4* 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10*10}\\\mathsf{= 100}\\\\\mathsf{4*100}\\\mathsf{= 400}


\large\text{NEW EQUATION: 700,000 + \bf 400}


\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}


\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}
