Exponents

Match the following:

the square of an integer (1, 4, 9, 16, 25, 36, 49, 64, 81, 100)

Perfect cube

the cube of an integer (8, 27, 64, 125)

Square root

opposite of an exponent of 2 (ex: 3 is the square root of 9 because 3x3=9)

Cube root

Exponents

Match the following:

a number that when written as a decimal it does not end or repeat (ex: 2.3587409873652974…)

Product rule

When you have an exponent raised to a power, keep the base and MULTIPLY the exponents

Irrational number

multiply 2 powers with the same base, keep the common base and ADD the exponents

Power rule

_ x 10^exponent 

where the first number is between 1-10 (one digit before the decimal)

Slope

Match the following

the point on the graph where the line crosses the y-axis (what is y when x=0)

X-intercept

the change in y divided by the change in x (or rise over run)

Slope intercept form

the point on the graph where the line crosses the x-axis (what is x when y=0)
