Answer 2

Answer:

The conjugate of (2√5 - 5√2) is (2√5 + 5√2)

Explanation:

• In mathematics, conjugates are expressions with same or identical  terms but different arithmetic operations.
• For any number of the form a + bx, its conjugate is given by replacing the + sign in the middle by a - sign
• Thus the conjugate of a + bx becomes a - bx
• Similarly, for the term (2√5 - 5√2), we see that there is a - sign in the middle of it, so to find its conjugate we simply change it to a + sign.
• Therefore, we get that the conjugate of (2√5 - 5√2) is (2√5 + 5√2)
