A baseball player hits a ball at an angle of 56° and at a height of 4.2 ft. If the ball’s initial velocity after being hit is 154 ft./s and if no one catches the ball, when will it hit the ground? Remember that the acceleration due to gravity is 32 .

The power of the root of the power of a variable can be written as a rational power by creating a rational exponent that is the product of the powers divided by the root. The rational exponent should be reduced to lowest terms. For example, the seventh power of the sixth root of the fifth power of x will be x^(7*5/6) = x^(35/6).
hope it helps
