Using the numbers [15, 73, 4, 34], create an equation that equals 254. You can use basic arithmetic operations (+, -, *, /) and each number can only be used once. Note that 4 and 73 are prime and cannot be combined in any creative way to reach the target quickly, but you might combine them using exponentiation, such as 73**1.5. Show your work in <think> </think> tags. And return the final equation and answer in <answer> </answer> tags, for example <answer> (15 + 73) * 4 = 364 </answer>.<|im_end|>
