After a lesson on exponents, Tia went home and said to her mom, “I learned that 104 is the same as 40,000.” She has made a mistake in her thinking. Use words, numbers, or a place value chart to help Tia correct her mistake.
Tia's mistake is that 10⁴ equals 10,000, not 40,000. She incorrectly multiplied the base of 10 by the exponent of 4 (10 x 4 = 40) and then added zeros, instead of multiplying 10 by itself 4 times.
