Answer 1

To simplify the expression, raise -1 to the power of 3, find the square root of the square root of 42, and subtract 7.

Step-by-step explanation:

To simplify the expression (-1)³+√√42-7, we need to follow the order of operations. First, we raise -1 to the power of 3, which gives us -1. Next, we need to find the square root of the square root of 42. The square root of 42 is approximately 6.48, and the square root of 6.48 is approximately 2.54. Finally, we subtract 7 from the result we obtained, which is 2.54. Therefore, the simplified expression is 2.54.
