Answer

(i) -2p3q2

Numerical coefficient = −2, Literal coefficient = p3q2

(ii) 59xyz2\dfrac{5}{9}xyz^2

Numerical coefficient = 59\dfrac{5}{9}, Literal coefficient = xyz2

(iii) 3ab22-\dfrac{3ab^2}{2}

Numerical coefficient = 32-\dfrac{3}{2}, Literal coefficient = ab2

(iv) 3a2\dfrac{3}{a^2}

Numerical coefficient = 3, Literal coefficient = 1a2\dfrac{1}{a^2}

(v) 2abc\dfrac{2ab}{c}

Numerical coefficient = 2, Literal coefficient = abc\dfrac{ab}{c}

(vi) 2x2yz-\dfrac{2x^2}{yz}

Numerical coefficient = -2, Literal coefficient = x2yz\dfrac{x^2}{yz}
