After a lesson on exponents, tia went home and said to her mom,"i learned that 10 to the power of 4 is the same as 40,000." she has made a mistake in her thinking. use words, numbers, or a place value chart to tia correct her mistake. show the actual solution

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^
