To write 17.002 in expanded form, you break it down into its place values. This can be expressed as (10 + 7 + 0.00 + 0.002), which simplifies to (10 + 7 + 0 + 0.002). Thus, the expanded form is (10 + 7 + 0.002).
Seven squared is 49, or 49.0 in decimal form.
If you mean 7x^3, you would write 7x*x*x . If you mean (7x)^3, you would write x*x*x*7*7*7. Exponential form just means you write it in the expanded form. For instance, 7 squared really means 7 times 7. So instead of writing 7^2, you would write 7*7
