Answer: (c^4d^5)^3(c^2d^7)^d=c^24d^57
Explanation:
(c^4d^5)^3x(c^2d^7)^6
(c^4d^5)^3 : c^12d^15
=c^12d^15x(c^2d^7)^6
(c^2d^7)^6 : c^12d^42
=c^12d^15xc^12d^42
Exponent rule-
a^b*a^c=a^b+c
=d^15xc^12+12d^42
Add the ^12+12
=d^15xc^24d^42
Exponent rule a^b*a^c=a^b+c
=xc^24d^15+42
Add the ^15+42
=xc^24d^57
