Standard Form: 2,503,000

Answer 2

Hey there!

`\mathsf{(3 * 10^3) + (2.5 * 10^6)}`

`\mathsf{= 3 * 10^3 + 2.5 *10^6}`

`\mathsf{10^3}`

`\mathsf{= 10 * 10 * 10}`

`\mathsf{= 100 * 10}`

`\mathsf{\bf = 1,000}`

`\mathsf{10^6}`

`\mathsf{= 10 * 10 * 10 * 10 * 10 * 10}`

`\mathsf{= 100 *100 *100}`

`\mathsf{= 10,000*100}`

`\mathsf{= \bf 1,000,000}`

`\mathsf{= 3* 1,000 + 2.5 * 1,000,000}`

`\mathsf{3*1,000}`

`\mathsf{\bf = 3,000}`

`\mathsf{2.5 * 1,000,000}`

`\mathsf{\bf = 2,500,000}`

`\mathsf{3,000 + 2,500,000}`

`\mathsf{= \bf 2,503,000}`

`\boxed{\boxed{\large\textsf{Answer: } \mathsf{ \bf 2,503,000 \ or \ 2.503 * 10^6}}}\huge\checkmark`

`\large\textsf{Good luck on your assignment and enjoy your day!}`
