Obtain answer =1
With full explanation ​

Answer 1

Answer:

-701757

Step-by-step explanation:

27^-2/3 × 81^5/4

= 79/3 x 329/4

= LCM= 12

= 79/3×4 = 316/12

= 329/4×3 = 987/12

= 316/12 × 987/12

= 316×987/ 12

= 158×987/ 6

= 155946/ 6

= 25991

now, we must solve the by form

(1/3)-³

= -1/3 × -1/3 × -1/3

= -1/27

now this is the final process to get the answer

= 25991/ (-1/27)

= (25991/1) × -(27/1)

(+ × - = -)

= - 701757
