Question

Write each number in expanded form using exponent Four and eighty_three thousandth

Answer 1

Four is simply written as 4.
83000 is written as 80000+3000

Now, your grammar and unusual spelling means that you might be talking about 483000, which would be 400000+80000+3000

Hope this helps

Answer 2

(4 x 1) + (0 x 0.1) + (8 x 0.01) + (3 x 0.001) = 4.083
