Question

If a*b = ab /a+b ,find the value of 3*(3*(-2))​

Answer 1

Answer:

6

Step-by-step explanation:

3*(-2)= 3(-2)/3-2=-6

3*(-6) = 3(-6)/(3-6) = -18/(-3) =6

Answer 2

Answer:

The value of 3$\times$ (3 $\times$ (-2))  is 6.

Given:

If a $\times$ b = $\frac{ab}{a+b}$,

To find:

Find the value of 3$\times$ (3 $\times$ (-2))

Solution:

The expression is 3$\times$ (3 $\times$ (-2))

Simplifying the expression in a \times b form, we get

= 3 $\times$ -6

$\frac{ab}{a+b}$,  

3 $\times$  (-6 ) =$\frac{(3 \times -6)}{(3 - 6)}$

= $\frac{-18}{-3}$ = 6

(since - divided by - = +)

The answer is 6.

Result:

The value of 3$\times$ (3 $\times$ (-2))   is 6.
