When can numbers with exponents be divided?
2
New cards
subtract the numerator’s exponent with the denominator’s exponent (leave base as is)
How do you divide exponents with the same base?
3
New cards
plug in numbers to the equation and answer choices to see if it matches
What can you do if you’re looking for the equivalent equation?
4
New cards
sin(90-x)=cosx
the sin of an angle is equal to the cos of it’s complement
5
New cards
plug in answers starting with the smallest number
What should you do when the question asks for the least possible value?
6
New cards
