Q. 35.0( 1 Vote )

Find out the product :

(i) 2a, 3a2, 5a4

(ii) 2x, 4y, 9z

(iii) ab, bc, ca

(iv) m, 4m, 3m2, - 6m3

(v) xyz, y2z, yx2

(vi) lm2, mn2, ln2

(vii) -2p, -3q, -5p2

Answer :

i. 2a, 3a2, 5a4


= (2 3 5) (aa2a4)


= (30) (a1 + 2 + 4)


= 30 a7


ii. 2x, 4y, 9z


= (24(x


= 72xyz


iii. ab, bc, ca


= abbc


= axaxbxbxcxc


= a2 b2 c2


iv. m, 4m, 3m2, - 6m3


= mx4mx3 m2x- 6m


= (43 m2 m3)


= -72( m1 + 1 + 2 + 3)


= -72 m7


v. xyz, y2z, yx2


= (x x2)


= (x1 + 2) ( ) ( )


= (x3) (y4) ()


= x3y4


vi. lm2, mn2, ln2


= ( l


=


=


vii. -2p, -3q, -5p2


= (-2 p2)


= (-30) p1 + 2


= -30 p3q
