1. Recognize the formula for the square of a binomial:
(a+b)^2 = a^2 + 2ab + b^2

2. Let \( a = 7m \) and \( b = 6n \).

3. Calculate \( a^2 \):
(7m)^2 = 49m^2

4. Calculate \( 2ab \):
2 \cdot (7m) \cdot (6n) = 84mn

5. Calculate \( b^2 \):
(6n)^2 = 36n^2

6. Combine these results:
49m^2 + 84mn + 36n^2

Answer:

49m^2 + 84mn + 36n^2

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
