the operation * is defined on the set R of all real number by 2a +3b ÷ a +b evaluate 2*(3*4)​

9514 1404 393

  2*(3*4) = 41/16

Step-by-step explanation:

Your function is not carefully defined.* We assume you intend ...

  f(a, b) = (2a +3b)/(a +b)

and you want to find ...

  f(2, f(3, 4))

__

Filling in the values and doing the arithmetic, we have ...

_____

* We have assumed that the definition is describing the result of using the infix operator * in an expression of the form a*b. We have also assumed that your use of the ÷ symbol means ...

  a*b ≡ (2a+3b)/(a+b)

as opposed to the strict Order of Operations interpretation ...

  a*b ≡ 2a + (3b/a) +b

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
