Let * be a binary operation on set of integers I, defined by a*b=2a+b-3. Find the value of 3*4.

Text Solution

Verified by Experts

Given that * is a binary operation on the set I of integers.
the operation is defined by `a`*`b = 2a + b – 3`.
We need to find the value of `3`*`4`.
Since `3` and `4` belongs to the set of integers we can use the binary operation.
`3`*`4=(2xx3)+4–3`
`3`*`4=6+1`
`3`*`4=7`
`therefore`the value of `3`*`4` is `7`.
