Let’s Review • Distributive Property • Classify Numbers • Order of Operations • B.A.G.
“I can…” • …find/approximate the square root or cube root of a number and evaluate expressions that contain radicals • M(N&O)-10-2 • M(N&O)-10-6
Types of numbers Real Numbers Irrational Numbers 3.14159265…. -21.1983956… Rational Numbers: p/q Integers…-3 -2 -1 0 1 2 3.. Whole Numbers: 0 1 2... Natural Numbers: 1 2 3 4 5…
A “Square” root • …is one of two equal ‘factors’ of a number • Ex. 4 is a square root of 16 • If a number has a square root that is a whole number, then it is a “perfect square.”
Graph • We use a “rational approximation”
