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
