The value of which of these expressions is closest to [tex]e[/tex]?

A. [tex]\left(1+\frac{1}{12}\right)^{12}[/tex]
B. [tex]\left(1+\frac{1}{14}\right)^{14}[/tex]
C. [tex]\left(1+\frac{1}{13}\right)^{13}[/tex]
D. [tex]\left(1+\frac{1}{11}\right)^{11}[/tex]



Answer :

Let's evaluate each expression and compare their values to the mathematical constant [tex]\( e \)[/tex], which is approximately [tex]\( 2.718281828459045 \)[/tex].

1. Expression A: [tex]\(\left(1+\frac{1}{12}\right)^{12}\)[/tex]

We calculate:
[tex]\[ \left(1+\frac{1}{12}\right)^{12} \approx 2.613035290224676 \][/tex]

2. Expression B: [tex]\(\left(1+\frac{1}{14}\right)^{14}\)[/tex]

We calculate:
[tex]\[ \left(1+\frac{1}{14}\right)^{14} \approx 2.6271515563008685 \][/tex]

3. Expression C: [tex]\(\left(1+\frac{1}{13}\right)^{13}\)[/tex]

We calculate:
[tex]\[ \left(1+\frac{1}{13}\right)^{13} \approx 2.6206008878857308 \][/tex]

4. Expression D: [tex]\(\left(1+\frac{1}{11}\right)^{11}\)[/tex]

We calculate:
[tex]\[ \left(1+\frac{1}{11}\right)^{11} \approx 2.6041990118975287 \][/tex]

Next, we find the difference between each calculated value and [tex]\( e \)[/tex]:

1. Difference for Expression A:
[tex]\[ |2.613035290224676 - 2.718281828459045| \approx 0.105246538234369 \][/tex]

2. Difference for Expression B:
[tex]\[ |2.6271515563008685 - 2.718281828459045| \approx 0.0911302721581765 \][/tex]

3. Difference for Expression C:
[tex]\[ |2.6206008878857308 - 2.718281828459045| \approx 0.0976809405733142 \][/tex]

4. Difference for Expression D:
[tex]\[ |2.6041990118975287 - 2.718281828459045| \approx 0.1140828165615163 \][/tex]

Upon comparing these differences:
- The difference for Expression A is approximately [tex]\( 0.1052 \)[/tex]
- The difference for Expression B is approximately [tex]\( 0.0911 \)[/tex]
- The difference for Expression C is approximately [tex]\( 0.0977 \)[/tex]
- The difference for Expression D is approximately [tex]\( 0.1141 \)[/tex]

We see that the smallest difference from [tex]\( e \)[/tex] is for Expression B.

Therefore, the value of the expression [tex]\(\left(1+\frac{1}{14}\right)^{14}\)[/tex] is closest to [tex]\( e \)[/tex].
