Question

44. The value of √7+2√10 is
(a) 1+√6 (6) √3+√4
(c) √2+ √5 (d) 2+ √5​

Answer 1

Answer:

√7+2√10=2.645+2(3.162)

=8.969

But, √[7+2√10]=3.650

(a)1+√6=1+2.449=3.449

(b) √3+√4=1.732+2=3.732

(c) √2+√5=1.414+2.236=3.650

(c) 2+√5=2+2.236=4.236

So, none of the above matches to the value of √7+2√10

So, the answer to your question is (c)√2+√5
