If (25^{x}=5^6), then (x=)?

Answer and explanation

Correct answer: (3)

Since 25 can be written as a power of 5, \(25=5^2\). Therefore, \(25^x=(5^2)^x=5^{2x}\). In \(5^{2x}=5^6\), the bases are equal, so the exponents must be equal: \(2x=6\), giving \(x=3\). Hence, option B is correct. Exam tip: When exponential expressions have the same base, equate their exponents.
