Answer:
What you have written is actually:
12√+3–√+5–√
[Why? Convention re the order of operations; just like 12/2+1+3 = 6+1+3=10]
The only denominator in this expression is the surd √2
To remove this surd, we just need to multiply the numerator and denominator by √2, thus we have:
12√×2√2√+3–√+5–√
=2√2+3–√+5–√
Somehow, I don’t think this is what you meant!
