Answer:
1: (ab)^3
2: 3m^2n^5
3: 15y^3x^7
4: 8s^5r^7
5: 6q^3p^5
Step-by-step explanation:
sorry but fot the explanation, it would take me 10 years to write but you can trust me with these answers
There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
