1.Let (a+bx+cx2)10=∑i=020pixi(a + bx + cx^{2})^{10} = \sum_{i=0}^{20} p_{i} x^{i}(a+bx+cx2)10=∑i=020pixi, a,b,c∈Na, b, c \in \mathbb{N}a,b,c∈N. If p1=20p_{1} = 20p1=20 and p2=210p_{2} = 210p2=210, then 2(a+b+c)2(a + b + c)2(a+b+c) is equal toa.666b.151515c.121212d.888Login to continueOnly logged in users canattempt or see the solution.
