1) Give an example of a binomial in the form a√b+c√d and its conjugate. Then find their product.

2) A spacecraft leaving earth must have a velocity of at least 11.2 kilometers per second (25,000 miles per hour) to enter into orbit. This velocity is called escape velocity. The escape velocity of an object is given by the radical expresision √2GM/R, where G is the gravitation constant, M is the mass of the planet or star, and R is the radius of the planet or star, and R is the radius of the planet or star. Once values are substituted for the variables, the formula can be simplified. Use the information above to explain explain how radical expression can be used in space exploration. Include an explanation of how you could determine the escape velocity of a planet and why you would need this information before you landed on it.
