Can you use the numbers [10, 30, 41, 7], along with the basic arithmetic operations (+, -, *, /), to reach the target number of 121? Each number can only be used once and show your work in <think> </think> tags. Finally, return the final equation and the answer in a <answer> to provide a thorough demonstration of your solution. For instance, if you find the equation 10 + 30 * (41 - 7) = 121, present it like this <answer> 10 + 30 * (41 - 7) = 121 </answer>.<|im_end|>
