4(4/5) + √(4/5) + 0.2 - 5(4/5)
= 16/5 + (2√5/5) + (1/5) - 4
= (16 + 2√5 + 1 - 20)/5
= (2√5 - 3)/5 or 0.29442719
Relationship 2 is a function because x isn’t being repeated.
Answer:
-1/20
Step-by-step explanation:
2(3/8) - 4/5
6/8 - 4/5
30/40 - 32/40
-2/40
-1/20
A. This is correct. When you transfer n to the other side, that would be the reciprocal power of a.
b. This is incorrect, because this contradicts with choice a.
c. This is correct. When a number is raised to a "1/n" fraction, that is equivalent to the nth root of the number.
d. This is incorrect, because it is not equivalent to the given equation.
<em>Thus, the answers are A and C.</em>
