other number to itself
opposite of multiplication, repeated subtraction, one number tells
Division
you how many parts to divide the other number into
superscript number placed at top right, indicates how many times to
Exponent
multiply base number by it self
PEMDAS, multiplication and division/addition and subtraction have
Order of operations
equal weight so they are completed left to right in order
1) Any number to the power of 1 is equal to itself: 𝑎^1 = 𝑎.
2)The number 1 raised to any power is equal to 1: 1^𝑛 = 1.
3)Any number raised to the power of 0 is equal to 1: 𝑎^0 = 1.
4) Add exponents to multiply powers of the same base number:𝑎^𝑛 × 𝑎^𝑚 =
𝑎^(𝑛+𝑚).
Laws of exponents 5) Subtract exponents to divide powers of the same number; that is 𝑎^𝑛 ÷ 𝑎^𝑚 =
𝑎^(𝑛−𝑚).
6) Multiply exponents to raise a power to a power: (𝑎^𝑛)^𝑚 = 𝑎^(𝑛×𝑚).
7) If multiplied or divided numbers inside parentheses are collectively
raised to a power, this is the
same as each individual term being raised to that power: (𝑎 × 𝑏)^𝑛 = 𝑎^𝑛 × 𝑏^𝑛; (𝑎 ÷
𝑏)^𝑛 = 𝑎^𝑛 ÷ 𝑏^𝑛
another way of writing a fractional exponent, √𝑎 (with n in the upper
Roots
