Question

what is the answer to this question? :)

Answer 1

Answer:

21

Step-by-step explanation:

[(c^5)^4]/c^x = c^-3 × c^2

c^4×5/c^x = c^-3+2

since c^20-x = c^-1

therefore 20 - x = -1

20 = x-1

20+1 = x

21 = x

Answer 2

Answer:

answer is a)21

Step-by-step explanation:

(c^5)^4/c^x=c^-3*c^2

c^20/c^x=c^-3+2

c^20/c^-1=c^x

c^20*c^1=c^x

c^21=c^x

(when bases are same powers get added)

21=x
