Question

Find value of (64)^(- ⅔)x(27)^(-⅔)​

Answer 1

Answer:

1/144

Step-by-step explanation:

(64)^(- ⅔)x(27)^(-⅔)

(4^3)^(- ⅔)x(3^3)^(-⅔)

4^(-2)x3^(-2)

(1/16)x(1/9)

1/144

Answer 2

Answer:

64 can be written in form of 4 's cube so 27 can be written as 3's cube

then,

(4)^3×-2/3×(3)^3×-2/3

so, 4^-2×3^-2

1/16×1/9

1/144
