Question

Among the following not a polynomial (a) 5x square - 5x+3 (b) 2 -3y +6y-2y square (c) xcube -3x+2 (d) x 3/4 -7x+4

Answer 1

$its \: option(d) \\ \\ here \: the \: power \: of \: {x}^{ \frac{3}{4} } is \: \frac{3}{4} \\ \\ which \: is \: not \: a \: natural \: number \\ \\ the \: power \: of \: x \: in \: any \: polynomial \: \\ \\ should \: belongs \: to \: natural \: number \\ \\ thats \: why \: option \: d \: is \: not \: a \: polynomial \\ \\ hope \: this \: helps \: you$
