Example Question #1 :How To Find A Ratio Of Exponents
Ifand, then which of the following CANNOT be the value of?
Even roots of numbers can either be positive or negative. Thus, x = +/- 5 and y = +/- 3. The possible values from x + y can therefore be:
(-5) + (-3) = -8
(-5) + 3 = -2
5 + (-3) = 2
5 + 3 = 8
Example Question #1 :How To Find A Ratio Of Exponents
Iffor allnot equal to 0, which of the following must be true?
Remember that
Since the problem states that, you can assume that
This shows that.
Example Question #1 :Exponential Ratios
Ifandare positive integers and, then what is the value of?
43= 64
Alternatively written, this is 4(4)(4) = 64 or 43= 641.
Thus,m= 3 andn= 1.
m/n= 3/1 = 3.
Example Question #811 :Algebra
Write the following logarithm in expanded form:
Example Question #812 :Algebra
Ifandare both rational numbers and, what is?
This question is asking you for the ratio of m to n. To figure it out, the easiest way is to figure out when 4 to an exponent equals 8 to an exponent. The easiest way to do that is to list the first few results of 4 to an exponent and 8 to an exponent and check to see if any match up, before resorting to more drastic means of finding a formula.
And, would you look at that.. Therefore,.
