The value of √0.04+√1.44+√1.69+√0.0009 is || ADRE 1.0 SLRC 2022 PAPER-III SOLVED QUESTIONS

The value of √0.04+√1.44+√1.69+√0.0009 is:

(A) 1.73 

(B) 2.03

(C) 2.73

(D) 1.03




Solution:

To find the value of √0.04+√1.44+√1.69+√0.0009, we will first compute the square roots of each term individually. 


√0.04

= √(4*0.01)

= √4*√0.01

= 2*0.1

= 0.2


√1.44= 1.2


√1.69= 1.3


√0.0009

= √(9*0.0001)

= √9*√0.0001

= 3*0.01

= 0.03


Now, let's add these values together:

0.2 + 1.2 + 1.3 + 0.03

= 2.73


Therefore, the value is (C) 2.73
