After a lesson on exponents, tia went home and said to her mom, "i learned that 10exponet 4 is the same as 40,000." she has made a mistake her thinking. use words to tia correct her mistake

10 exponent 4 is not the same as 40 000. Tia’s thinking is definitely wrong.
Because exponent is a number that indicates how many times you will going to  multiply the base number.
Let’s show how we do it:
=> 10 ^ 4
=> 10 x 10 x 10 x 10 , where 10 is our base number and 4 is our exponent. So we multiply 10 4 times
=> 10 000 = the correct answer to the given equation.

Ibelieve the total for the tip could be $21.90
