To solve the problem, we need to find the correct representation for the expression \( 5 = 7^{\log_7 5} \).
1. Understanding Logarithmic Properties:
We can use the property of logarithms which states:
\[
a^{\log_a b} = b
\]
This property implies that \( 7^{\log_7 5} = 5 \), because the base and the logarithm's base are the same.
2. Verifying the Options:
The given equation \( 5 = 7^{\log_7 5} \) corresponds exactly to Option (3):
\[
7^{\log_7 5}
\]
Final Answer:
The correct option is Option C: \( 7^{\log_7 5} \).
Consider two distinct positive numbers \( m, n \) with \( m > n \). Let \[ x = n^{\log_n m}, \quad y = m^{\log_m n}. \] The relation between \( x \) and \( y \) is -
If \[ \log_{p^{1/2}} y \times \log_{y^{1/2}} p = 16, \] then find the value of the given expression.
