Solving the Exponential Equation: (25)^x-1 = 64(5/2)^6

This article will guide you through solving the exponential equation (25)^x-1 = 64(5/2)^6. We will utilize the properties of exponents and logarithms to arrive at the solution.

Simplifying the Equation

  1. Express both sides with the same base:
    • We can rewrite 25 as 5^2 and 64 as 2^6.
    • The equation now becomes: (5^2)^(x-1) = 2^6 (5/2)^6.
  2. Apply exponent rules:
    • (a^m)^n = a^(m*n)
    • The equation becomes: 5^(2x-2) = 2^6 * 5^6 / 2^6
  3. Simplify further:
    • The 2^6 terms cancel out, leaving: 5^(2x-2) = 5^6

Solving for x

  1. Equate the exponents:
    • Since the bases are the same, we can equate the exponents: 2x - 2 = 6.
  2. Solve the linear equation:
    • Add 2 to both sides: 2x = 8.
    • Divide both sides by 2: x = 4.

Conclusion

Therefore, the solution to the exponential equation (25)^x-1 = 64(5/2)^6 is x = 4.
