Help meeeeeeeeeeee:(
Vaselesa [24]

Answer:

1/3

Step-by-step explanation:

(1/3)^2x(1/3)^-1

so, we can write this as:

1/3 x 1/3 x 3/1

if calculated by cutting, the answer is 1/3

There is also an easier way to do this,

(1/3)^2 x (1/3)^-1

as the bases are same, the powers will be added.

2+(-1)

2-1

=1

so,

(1/3)^1 or 1/3
