Multiple Choice

Use the binomial theorem to expand the binomial. $$\left( \frac { a } { 2 } + t \right) ^ { 4 }$$

• A) \(\quad a ^ { 4 } + a ^ { 3 } t + a ^ { 2 } t ^ { 2 } + a t ^ { 3 } + t ^ { 4 }\)
• B) \(\quad \frac { 1 } { 8 } a ^ { 4 } + \frac { 1 } { 2 } a ^ { 3 } t + \frac { 3 } { 2 } a ^ { 2 } t ^ { 2 } + 2 a t ^ { 3 } + t ^ { 4 }\)
• C) \(\quad \frac { 1 } { 2 } a ^ { 4 } + t ^ { 4 }\)
• D) \(\quad \frac { 1 } { 16 } a ^ { 4 } + \frac { 1 } { 2 } a ^ { 3 } t + \frac { 3 } { 2 } a ^ { 2 } t ^ { 2 } + 2 a t ^ { 3 } + t ^ { 4 }\)
• E) \(\quad \frac { 1 } { 16 } a ^ { 4 } + \frac { 1 } { 8 } a ^ { 3 } t + \frac { 1 } { 4 } a ^ { 2 } t ^ { 2 } + \frac { 1 } { 2 } a t ^ { 3 } + t ^ { 4 }\)
