Using the numbers [1, 23, 45, 77], create an equation that equals 50. The target needs to be obtained using basic arithmetic operations (+, -, *, /), and each number can only be used once. Show your work in <think> </think> tags. Here are some arithmetic operations to help guide your solution: multiplication (shifted right, *) or division (floor division, //), exponentiation (**), adding a number to itself (e.g. **2), and subtracting a number from another (e.g. **1 - **1). Show your final equation step-by-step, showing each operation used to get the answer, in the <answer> </answer> tag. For example, <answer> (x1 ** 2) / x2 - x3 = x4 </answer>.<|im_end|>
