Hi! Here is your answer for this question!
Answer... (7•10^5)+(2•10^4)+(8•10^1)
Steps...
Place your numbers that is in your question into a place value form, with your exponents.
Place Value form...
Hundred-Thousands Ten-Thousands Thousands Hundreds Tens Ones
7 (10^5) 2 (10^4) 0 (10^3) 0 (10^2) 8 (10^1) 0 (1)
Expanded form + exponents... 7•10^5+2•10^4+0•10^2+8•10+0 (We obviously know that 0 times itself or any other number is 0.)
7•10^5+2•10^4+0•10^2+8•10+0 = (7•10^5)+(2•10^4)+(8•10^1)
I hope this helps you! Good luck!
