Question

Use the following identity: (a+b) (a-b)=a square-bsquare​

Answer 1

$(0.1m - 0.2n)(0.1m + 0.2n) \\ \\ {(0.1m)}^{2} - {(0.2n)}^{2} \\ {0.01m}^{2} - {0.04n}^{2}$

Answer 2

Answer:

0.01m^2-0.04n^2

Step-by-step explanation:

(0.1m-0.2n)(0.1m+0.2n)

(a+b)(a-b)=a^2-b^2

(0.1m)^2-(0.2n)^2

(0.01m^2)-(0.04n^2)

0.01m^2-0.04n^2
