What is the value of the expression below?

[tex]\[ \left(15^{1/\pi}\right)^5 \][/tex]

A. 1
B. 8
C. 15
D. 243


Sagot :

To solve the given expression \(\left(15^{1/\pi}\right)^5\), we follow a step-by-step process.

First, interpret the notation correctly:
[tex]\[ \left(15^{1/\pi}\right)^5 \][/tex]

Next, remember the property of exponents which states: \((a^m)^n = a^{m \cdot n}\). We can use this property to simplify our expression. In our case, \(a = 15\), \(m = 1/\pi\), and \(n = 5\):

[tex]\[ \left(15^{1/\pi}\right)^5 = 15^{(1/\pi) \cdot 5} \][/tex]

Now we need the value of \((1/\pi) \cdot 5\):
[tex]\[ (1/\pi) \cdot 5 = \frac{5}{\pi} \][/tex]

Thus, our expression is simplified to:
[tex]\[ 15^{5/\pi} \][/tex]

Now let's evaluate \(15^{5/\pi}\). Given the true results, we know that:

[tex]\[ 15^{1/\pi} \approx 2.3678897349212167 \][/tex]

Raising this value to the power of 5 gives us:
[tex]\[ (2.3678897349212167)^5 \approx 74.44017305013445 \][/tex]

Hence, the value of the original expression \(\left(15^{1/\pi}\right)^5\) is approximately \(74.44\).

Since none of the provided options match this result exactly:
- A. 1
- B. 8
- C. 15
- D. 243

None of the given answer choices is correct.
