What does the equation x to the power y equals 25 really mean? This is an exponential equation where x is the base and y is the exponent. It means when we multiply x by itself y times, the result is 25. So we're asking: what base number, when raised to a certain power, gives us 25?
Exponential notation represents repeated multiplication. For example, 2 to the power 3 means 2 times 2 times 2, which equals 8. The exponent tells us how many times to multiply the base by itself. This same principle applies to our equation x to the power y equals 25.
Let's find specific solutions to x to the power y equals 25. If x equals 5, then 5 squared equals 25, so y equals 2. If x equals 25, then y must be 1, because 25 to the first power equals 25. We can also have negative 5 squared equals 25, since negative 5 times negative 5 equals positive 25.
Solutions aren't limited to integers! For any positive x not equal to 1, there exists a value y such that x to the power y equals 25. For example, if x equals square root of 5, then y equals 4. If x equals 2, then y is approximately 4.644. This relationship forms a curve described by y equals log base x of 25.
To summarize, x to the power y equals 25 is an exponential equation where x is the base and y is the exponent. We found multiple solutions including integers like 5 squared and 25 to the first power, as well as non-integers. This equation can be rewritten using logarithms as y equals log base x of 25. Exponential equations like this appear frequently in real-world applications such as compound interest, population growth, and radioactive decay.
