Math Problem Statement

What is X=?

Solve (√6)^(2x) = (√6)^(x+6).

Solution

To solve the equation:

(63)2x=(6)x+6\left( \sqrt[3]{6} \right)^{2x} = \left( \sqrt{6} \right)^{x + 6}

First, let's express the radicals as exponents:

  • 63=61/3\sqrt[3]{6} = 6^{1/3}
  • 6=61/2\sqrt{6} = 6^{1/2}

The equation then becomes: (61/3)2x=(61/2)x+6\left( 6^{1/3} \right)^{2x} = \left( 6^{1/2} \right)^{x+6}

Using the power rule (am)n=amn(a^m)^n = a^{m \cdot n}, we can simplify both sides:

62x3=6x+626^{\frac{2x}{3}} = 6^{\frac{x + 6}{2}}

Since the bases are the same (both are powers of 6), we can set the exponents equal to each other:

2x3=x+62\frac{2x}{3} = \frac{x + 6}{2}

Now, solve for xx by cross-multiplying:

2×2x=3×(x+6)2 \times 2x = 3 \times (x + 6) 4x=3x+184x = 3x + 18 4x3x=184x - 3x = 18 x=18x = 18

Thus, x=18x = 18.
