Question

Simplify: 255–√−296–√+145–√−66–√

Answer 1

To simplify the given expression, evaluate each square root and subtract from the previous result to get 242.958.

Step-by-step explanation:

To simplify the given expression, we need to evaluate each square root and then subtract the result from the previous one.

Starting with 255, the square root of -296 is not a real number, so we move on to the next term.

The square root of 145 is 12.042, and when subtracted from 255, we get 242.958.

Finally, the square root of -66 is also not a real number, so we subtract 0 from 242.958 to get the simplified result of 242.958.
