Answer:
0, for q ≠ 0 and q ≠ 1
Step-by-step explanation:
Assuming q ≠ 0, you want to find the value of x such that ...
q^x = 1
This is solved using logarithms.
__
x·log(q) = log(1) = 0
The zero product rule tells us this will have two solutions:
x = 0
log(q) = 0 ⇒ q = 1
If q is not 0 or 1, then its value is 1 when raised to the 0 power. If q is 1, then its value will be 1 when raised to <em>any</em> power.
_____
<em>Additional comment</em>
The applicable rule of logarithms is ...
log(a^b) = b·log(a)
Answer: 4 apples for $3.64
Step-by-step explanation:
The best buy is going to be the one that costs the least. To figure this out, you divide the number of apples by the price. (do not round)
4/3.64=1.09
9/8.01=1.23
14/12.43=1.12
24/21.12=1.13
As you can see, the 4 apples for $3.64 is the better choice since the number is the least.
