BELL WORK! Answer35 • 1. 7(14 – 9) • 2. • 3. 175 ÷ Answer7 Answer35
Order of Operations with exponents
Location of Exponent • An exponent is a little number high and to the right of a base number. Exponent 3 4 Base
What an Exponent Represents • An exponent tells how many times a number is multiplied by itself. 4 = 3 x 3 x 3 x 3 3
How to read an Exponent • This exponent is read three to the fourth power. Exponent 3 4 Base
How to read an Exponent • This exponent is read three to the 2nd power or three squared. Exponent 3 2 Base
How to read an Exponent • This exponent is read three to the 3rd power or three cubed. Exponent 3 3 Base
Read These Exponents 9 2 6 7 2 3 5 4
What is the Exponent? 3 2 x 2 x 2 = 2
What is the Exponent? 4 5 x 5 x 5 x 5 = 5
How to Multiply Out an Exponent 4 3 = 3 x 3 x 3 x 3 9 27 81
You Try: 3 5 125 =
PEMDAS 3 (9+1) + 62 3(10)+62 3(10)+36 30+36 66
PEMDAS 3+23- (9+1) 3+23- 10 3+8-10 11-10 1
PEMDAS 4+ 10 x 23 -16 4+10 x 8 -16 4+ 80 -16 84-16 68
PEMDAS 21 + 102 10 21+10010 21 + 10 31
PEMDAS 10+72-2 x 5 10+49–2 x 5 10+49- 10 59 - 10 49
Challenge!!20 - 3 • 6 + 102 + (6 + 1) • 4 = 20 - 3 • 6 + 102 + (7) • 4 (parentheses) = 20 - 3 • 6 + 100 + (7) • 4 (exponents) = 20 - 18 + 100 + (7) • 4 (Multiply l/r.) = 20 - 18 + 100 + 28 (Multiply l/r.) = 2 + 100 + 28 (Subtract l/r.) = 102 + 28 (Add l/r.) =130 (Add.)
