EXPONENTS:
What are the 3 parts of an exponent?
2x3
2 = co – efficient
X = base
3 = exponent
What are the 4 rules of exponents?
1. 2x2 + 3x2 (WHEN YOU ADD TERMS WITH EXPONENTS YOU ONLY ADD WHEN THE BASE
AND EXPONENT ARE THE SAME)
2. X2 x X3 (WHEN YOU TIMES TERMS WITH THE SAME BASE YOU ADD THE EXPONENTS)
3. (a2b4)2 ( WHEN YOU RAISE TERMS WITH EXPENENTS TO THE POWER OF ANOTHER
EXPONENT; YOU MULTIPLY THE EXPONENT)
4. X3y2 ÷ X2 (WHEN YOU DIDVIDE TERMS WITH SIMILAR BASES YOU SUBTRACT THE
EXPONENTS)
5. X2y2 + y2 X2
6. Xy x Xy
WHAT IS AN ALGEBRAIC EXPRESSION?
Variable = x; y, z etc.
Constant = x2 + 10 (it never changes)
Term = is a part of an equation. Are separated by + and – signs
Expressions = made up of terms and has no equals sign.
Equation = has = sign.
2x = 3
HOW THE NUMBER OF TERMS AFFECTS AN EPRESSION.
2x2 + 3x + 2 = Trinomial
2x + 2 = binomial
2x = monomial
LIKE AND UNLIKE TERMS
Base and exponent are the same
X2 and y2 = unlike terms.
3 and 5 = like terms (exception to rule)
Y2 + 2y2 = 3y2 – like terms
