In this unit, you will begin with a review of factors, prime numbers, and prime factorization. You will then work through perfect squares and square roots. The perfect squares should be numbers that you commit to memory, as this memorization will lead you to quick answers later. You may wish to create flashcards with the answers on the back to assist in your memorization. You can keep the cards and practice anytime. You will also apply your knowledge of square roots and estimation to approximate non-perfect square roots. You will also multiply and divide expressions involving exponents with a common base, take a power to a power, and take positive rational numbers to whole-number powers.
