expression 2
OpenStudy (mathstudent55):
1. Anytime you divide a number by itself, except for zero, the answer is 1.
OpenStudy (anonymous):
the first would be three because when the base is the same and you are dividing two powers all you do is takeaway the denominator from the numerator (4-4)
OpenStudy (mathstudent55):
2. Use the rule a^m/a^n = a^(m - n)
When you divide two powers that have the same base, subtract the exponents.

then 3/3 is equal to one
OpenStudy (mathstudent55):
@WilliamF 3^4/3^4 = 3^(4-4) = 3^0 = 1
OpenStudy (anonymous):
the answer is definetly 1
OpenStudy (anonymous):
is the second one 6
OpenStudy (anonymous):
sorry what I meant to say was, when the power is not equal to 0 then the base stays the same and you just minus the two powers

the second would be 2-5
so 2^-3
OpenStudy (mathstudent55):
2. 2^2/2^5 = 2^(2 - 5) = 2^(-3) = 1/2^3 = 1/8
