(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

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

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

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

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

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

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

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

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

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