Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\left. \begin{array} { l } { \cos e c \frac { 8 } { 4 } } \\ { \cos e ^ { 2 } 4 } \\ { \cos e ^ { 2 } \theta } \\ { = \cos e ^ { 2 } \theta } \\ { - \cot \theta } \end{array} \right.$$

Answer

$$84*os(e)*t^2*h*a*c^2+os(e)*c^2*o$$

Solution


Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[{t}^{2}ha{c}^{2}os(e)\times 84+cos(e)co\]
Regroup terms.
\[84os(e){t}^{2}ha{c}^{2}+cos(e)co\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[84os(e){t}^{2}ha{c}^{2}+{c}^{2}os(e)o\]
Regroup terms.
\[84os(e){t}^{2}ha{c}^{2}+os(e){c}^{2}o\]
