Questions & Step-by-Step Solutions

If 7^(x) = 49, what is the value of x?
  • Step 1: Start with the equation 7^(x) = 49.
  • Step 2: Recognize that 49 can be rewritten as a power of 7.
  • Step 3: Write 49 as 7^2, since 7 multiplied by itself (7 * 7) equals 49.
  • Step 4: Now the equation looks like this: 7^(x) = 7^2.
  • Step 5: Since the bases (7) are the same, we can set the exponents equal to each other: x = 2.
  • Step 6: Therefore, the value of x is 2.
  • Exponents – Understanding the properties of exponents and how to manipulate them to solve equations.
  • Base Conversion – Recognizing that 49 can be expressed as a power of 7.
