Answer:

Option B

Explanation:

Laws of indices:

1.
a^(n) =
(1)/(a^(-n)) OR
a^(-n) =
(1)/(a^(n))


2.
a^(n) ×
a^(m) =
a^(n + m)


3.
(a^(n))/(a^(m)) =
a^(n-m)




(6)/(3) ×
(x^(2))/(x^(6))

Method 1:

=
2 ×
(1)/(x^(6).x^(-2))

=
(2)/(x^(6+(-2)))

=
(2)/(x^(6-2))

=
(2)/(x^(4))


Method 2:

=
2 ×
x^(2-6)

=
2
x^(-4)

=
(2)/(x^(4))


∴Option B
