Let* be a binary operation on `N` given by a*b = HCF`(a ,\ b)\ a ,\ b\ \ Ndot` Write the value of 22*4.

Text Solution

AI Generated Solution

To solve the problem, we need to evaluate the binary operation defined by \( a * b = \text{HCF}(a, b) \) for \( a = 22 \) and \( b = 4 \). ### Step-by-Step Solution: 1. **Identify the operation**: We are given that the operation \( a * b \) is defined as the highest common factor (HCF) of \( a \) and \( b \). 2. **Substitute the values**: We need to find \( 22 * 4 \). According to the operation, this means we need to calculate \( \text{HCF}(22, 4) \). ...
