Answer :
Answer:
C
Step-by-step explanation:
Think of these radicals as variables, and assign them. Use sqrt7 as x and sqrt3 as y.
This gives an equation of 19x-22y+5x+6y.
We need to combine the like terms, grouping x's and y's. When we group like terms, we find 19x+5x-22y+6y.
Simplify that equation to get 24x-16y.
Now, we plug back sqrt7 and sqrt3 for x and y respectively. This gives the final answer 24sqrt7-16sqrt3.
Hope this helps!
