Answer: False
Step-by-step explanation: False because zero is negative or positive. The absolute value of any number could also include the absolute value of 0, which would be 0. Thus, the absolute value of any rational number is not always greater than zero, it can be zero as well. However, it is true that the absolute value of any rational number can never be negative.
Rational Number definition: Rationals contain whole numbers, integers, decimals, fractions, basically most numbers or any numbers.
Answer:
turn the fractions into decimals
7/20 = 0.35
1/5 = 0.20
the answer is
0.38 then 7/20 then 0.34 then 1/5
18/1
36/2
72/4
...and many more....
Fifth root of x is x^1/5 as an exponential expression. . This to the 7th power is
x ^(1/5 * 7) which is x^(7/5). Bringing this to the third power is x^ (21/5) which is your answer.
