UP Police Constable Exam Model Paper 4

Question : 108 of 150

Marks: +1, -0

The least number among

(0.5)^2,

$√ 0.49, ^3√0.008$ and 0.23 is

Solution:

Calculations:

(0.5)^2=0.5×0.5

⇒ 0.25

√ 0.49=√ (0.7×0.7)

⇒ 0.7

^3√ {0.008}=^3√ {0.2×0.2×0.2}

⇒ 0.2
Arranging the all above numbers in descending order
0.7 > 0.25 > 0.23 > 0.2
∴ The least number among all the numbers is $^3√0.008$
