How do you write 12,430,000 in expanded form

const2013 [10]

we know that

$12,430,000$ in expanded form is equal to

$12,430,000=1*(10,000,000)+2*(1,000,000)+4*(100,000)+3*(10,000)\\\\ 12,430,000=(10,000,000)+(2,000,000)+(400,000)+(30,000)$

therefore

<u>the answer is</u>

$(10,000,000)+(2,000,000)+(400,000)+(30,000)$
