Question

Positive square root of 7+√48

Answer 1

7+√48 = 7+√4×4×3 = 7+4√3

let it is the square of a+√b. (there must be in that format or you can see from the options also. All are in a+√b format)

so (a+√b)² = 7+4√3

(a+√b)² = a²+b + 2a√b = 7+4√3

comparing the terms,

2a√b = 4√3

⇒ a√b = 2√3

a=2, b=3

and it satisfies a²+b = 7

So the required number is a+√b = 2+√3
