If √24 + √96 - √600 = y√6, find the value of y
A
4
B
2
C
-2
D
-4
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
\sqrt24 + \sqrt96 - \sqrt600 = y\sqrt6
convert all to basic surds
\sqrt24 = 2\sqrt6
\sqrt96 = 4\sqrt6
- \sqrt600 = -10\sqrt6
2\sqrt6 + 4\sqrt6 - 10\sqrt6 = -4\sqrt6
value of y = -4
