Question

use a suitable identity to get each of the following products:-(m²-n²m)²+2m²n²​

Answer 1

Answer:

m^4 +(nm) ^4

Step-by-step explanation:

So (m^2 -[ nm] 2)+2m2n2

=> by the formula (a-b) ^2 = a2 +b2 - 2ab

After substituting value

=>m4 +nm4 - 2m2n2+2m2n2

Therefore the answer is m^4 +(nm) ^4
