Solution

The equation in the image is:

2x+2=232^{x+2} = \sqrt[3]{2}

To solve for xx, follow these steps:

  1. Rewrite the cube root as an exponent: 23=213\sqrt[3]{2} = 2^{\frac{1}{3}} Now, the equation is: 2x+2=2132^{x+2} = 2^{\frac{1}{3}}

  2. Since the bases are the same (both are base 2), you can set the exponents equal to each other: x+2=13x + 2 = \frac{1}{3}

  3. Solve for xx by subtracting 2 from both sides: x=132x = \frac{1}{3} - 2

  4. Simplify the right-hand side: x=1363=53x = \frac{1}{3} - \frac{6}{3} = \frac{-5}{3} Therefore, x=53x = -\frac{5}{3}.

The solution to the equation is x=53x = -\frac{5}{3}.
