Question

evaluate using identity: (2/3m+3/2n)^​

Answer 1

Answer:

In the question we have 2 terms

On squaring we will get the formulae of (a+b) ²

So, (2/3m + 3/2n)²

We know that (a+b) ² = a² +b² +2ab

So, (2/3m+3/2n)² = (2/3m)² + (3/2n)² + 2(2/3m)(3/2n)

= 4/9m² + 9/4n² + 2mn

Hope this will be helping you.
