​

Answer 1

Step-by-step explanation:

given root 12+ root 10- root2

=3.46+3.16-1.414

=6.62-1.41

=5.21

Answer 2

Answer:

√12+√10-√2

or √6.√2+√2.√5–√2

or √2(√6+√5–1)

On substituting √2=1.414, √5=2.236 & √6=2.449, we get:

1.414(2.236+2.449–1)

or 1.414(4.685–1)

or 1.414(3.685)

⇒√12+√10≈5.21
