Answer 1

Answer:

the square of  $(6m+7)^2$ is, $36m^2+84m+49$

Step-by-step explanation:

To find the square of  $(6m+7)^2$

Using the identity:

$(a+b)^2 = a^2+2ab+b^2$

Apply this identity on the given expression:

$(6m+7)^2$

⇒$(6m)^2+2(6m)(7)+7^2$

Simplify:

⇒$36m^2+84m+49$

Therefore, the square of  $(6m+7)^2$ is, $36m^2+84m+49$

Answer 2

( 6 m + 7 )² =

Apply distritutive rules:

(6m)² + 2 * 6 m * 7 + 7² =

6 m * 6 m + 2 * 6 m * 7 + 7*7 = 

36 m² + 84m + 49 

hope this helps!
