Q: If 3^(x) = 81, what is the value of x?
Solution:
81 = 3^(4), so x = 4.
Steps: 5
Show Steps
Step 1: Understand the equation 3^(x) = 81.
Step 2: Recognize that 81 can be expressed as a power of 3.
Step 3: Find the power of 3 that equals 81. We know that 3^(4) = 81.
Step 4: Since 3^(x) = 3^(4), we can set the exponents equal to each other.
Step 5: Therefore, x = 4.
