Step-by-step explanation:
when we Simplify (√5+√2)² we get the solution (√5)² + 2√5√2+ (√2)²= 5+2√10+2=7+2√10 how do we get 10?
Answer:
It is -2
well to cancel a square root a number should be possible to find its root (square) for example:
√24
√24=√4(6)
Since 4 is a perfect square we can simplify it
√4(6)=√2^2(6)
so √24=2√6
