1.	(16\25)power-1÷(4/5)power-3 find the rational number
Answer» Answer: 4/5 or 0.8 Step-by-step explanation: (16/25)^-1 ÷ (4/5)^-3 by the law of exponent a^-1 = 1/a so, it is (25/16)^1 ÷ (5/4)^3 you can write 25 as 5² and 16 as 4² so it will be 5²/4² ÷ 5³/4³ =5²/4² × 4³/5³ = 4/5 hope it HELPS... PLS MARK as brainliest if you are satisfied with my answer... thank you..

Answer:

4/5 or 0.8

Step-by-step explanation:

(16/25)^-1 ÷ (4/5)^-3

by the law of exponent

a^-1 = 1/a

so, it is

(25/16)^1 ÷ (5/4)^3

you can write 25 as 5² and 16 as 4² so it will be

5²/4² ÷ 5³/4³

=5²/4² × 4³/5³

= 4/5

hope it HELPS...
