Question

((-7/9)³ * (-9/7)-³ )÷ (-7/9)-³​

Answer 1

Answer:

[(-7/9)^3 *(-9/7)^-3  ]  ÷ (-7/9)^-3      we can write -9/7^-3 as -7/9 ^3

                                                           and -7/9^-3 as -9/7^3

= (-7/9^3 * -7/9^3) ÷ -9/7^3

= -7/9^3+3         ÷ -9/7^3

= -7/9^6 * -7/9 ^3

= -7/9 ^6+3

= -7/9 ^9
