Real #s - ANSWER-Irrational, rational, and whole #s
Find the distance between 2 pts. on # line - ANSWER-Take the absolute value of the
difference between the 2 pts.
d(P,Q) = | b - a |
Which values must be excluded from the domain of the variable in the expression? -
ANSWER-Substitute the variables into the problem - the denominator cannot equal 0.
Negative exponents - ANSWER-a⁻ⁿ = 1/aⁿ
Law of Exponents - ANSWER-(a×)ⁿ = a×·ⁿ
(a · b)ⁿ = aⁿ · bⁿ
(aⁿb*)^ = aⁿ^b*^
xⁿx* = xⁿ⁺*
xⁿyⁿ = (xy)ⁿ
xⁿ/x* = xⁿ⁻*
xⁿ/yⁿ = (x/y)ⁿ
x⁰ = 1
a⁰ = 1 if a ≠ 0
When multiplying exponents, you add them.
Cannot distribute exponents when adding or subtracting
Ex → (5x-7)²
Square roots - ANSWER-√a² = |a|
Tip: Rewrite expressions without negs or neg exponents - ANSWER-...
Circle - ANSWER-A = πr²
C = πd or 2πr
Rectangular box - ANSWER-v = l · w · h
S.A. = 2LH + 2WH + 2LW
