4.78 times 10 to the 6th power was the largest attendance record of the polar bear express. chilly football extravaganza. 3.98 times 10 to the 6th power attended at the last last pb express event. how many more people were in attendance on the record-setting day?

9514 1404 393

  8×10⁵ = 800,000

Step-by-step explanation:

The difference is ...

  (4.78×10⁶) -(3.98×10⁶) = 0.80×10⁶ = 8×10⁵

8×10⁵ = 800,000 more people attended at the largest extravaganza.

Your calculator (or a spreadsheet) can do the subtraction and display the number in whatever format you want.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
