Answer 1

Answer:

hii mate hope my answer finds u in the pink of ur health---

Step-by-step explanation:

(i)2x^1/6×2x^-7/6

=2x^1/6-7/6 since a^m×a^n=(a^m+n)

=2x^-6/6

=2x^-1

1^2x.

(ii)4 root under1/x^-12×-2/3

=4 sq.rt (1/x)^8

=4 sq.rt (1/x^8)

=4×1/x^4

=4/x^4.

(iii)a^4/7÷a^10/7

=a^4/7-10/7 since a^m÷a^n=(a^m-n)

=a^-6/7

=7sq.rt(1/a^6)

hope this helps u

be happy always
