(i) -2a^2 , 7a^2b^2 , 6 a^5b^5
= (-2 × 7 × 6 ) a × a × a × a× a × a× a× a× a× b× b× b× b× b× b× b
= -84a^9b^7

Step-by-step explanation:
i.-2a^2,7a^6b^7,6a^5b^5
=-(2*7*6)(a^2*a^6*a^5)(b^7*b^5)
=84a^13b^12
ii.-6/5xy,15/16yz,8/9xyz
=(-6/5*15/16*8/9)*(x*x)*(y*y*y)*(z*z)
=-1x^2y^3z^2
iii.7/9xy^2,15/7xz^2y,-3/5
=(7/9*15/7*(-3/5))(x*x)(y^2*y)*z^2
=-1x^2y^3z^2
iv.5a^4,(a^2)^3,(2a)^2
=5a^4*a^6*4a^2
=(5*1*4)(a^4*a^6*a^2)
=20a^12
v.2/3a^3bc^2,1/3a^2b^3c,9abc^3
=(2/3*1/3*9)(a^3*a^2*a)(b*b^3*b)(c^2*c*c^3)
=2a^6b^5c^6
vi.0.5a,1/3ab^3c^4,24a^2b
=(0.5*1/3*24)(a*a*a^2)(b^3*b)*c^4
=4a^4b^4*c^4
