Answer:
357.062 = 300 +50 +7 +0.0 +0.06 +0.002
Step-by-step explanation:
There are several ways "expanded form" can be written. You should choose a form that is consistent with your curriculum materials.
357.062 = 300 +50 +7 +0.0 +0.06 +0.002
357.062 = 3×100 +5×10 +7×1 +0×0.1 +6×0.01 +2×0.001
357.062 = 3×10² +5×10¹ +7×10⁰ +0×10⁻¹ +6×10⁻² +2×10⁻³

Additional comment
I like the last form because it clearly shows how the location of a digit in a place-value number system is related to the power of the base. This can be especially helpful when you start considering bases other than 10, or when you express a number in scientific notation.
