Question

.. If a = 3 and b = 2, find the value of (ab + ba)-1​

Answer 1

ab+ba-1

=3(2)+2(3)-1

=6+6-1

=11

Answer 2

Question :

If a = 3 and b = 2, find the value of (ab + ba)-1.

Solution :

Given that a = 3 and b = 2.

We have to find out the value of (ab+ba)-1.

==> [2(3)+3(2)]-1

==> [6+6]-1

==> 12-1

==> 11

So, the value of (ab+ba)-1 is 11 when a = 3 and b = 2
