Answer:
2nd and 4th expressions are equivalent.
Step-by-step explanation:
In this question we have been asked the equivalent expressions.
We take the second expression
-[tex]\frac{1}{5}k+\frac{2}{3}j[/tex]
We can rewrite this expression as
[tex]\frac{2}{3}j-\frac{1}{5}k[/tex]
I have flipped first and second terms of the original expression.
This changed expression is same as 4th expression given in the question.
Therefore, 2nd and 4th expressions are equivalent.
