Answer 2

Answer:

1/121

Step-by-step explanation:

( 1331 ) ^-2/3

= 1331 is 11^3 so, (11^3)^-2/3

= As cube inside the bracket is numerator, and 3 outside is denominator. So,3&3 gets cancelled.

∴ 11^-2

If we bring 11^-2 to the denominator we get 1/11^2

∵ 11 ^2 is 121

∴ ( 1331 ) ^-2/3 = 1/121
