Answer 2

Answer:

1

Step-by-step explanation:

as the bases are same powers can be directly equated

if the bases are same and are being multiplied the powers are added and uf the bases are same and are being divided then powers are subtracted

(3-¹ x 3-²) / 3 -³ can be written as

-1 + -2 / -3 = -3/-3

=>(3-³) / (3-³)

= 3^ ( -3 - (-3))

= 3^( -3+3)

= 3^0

=> 1

hence 1 is the answer
