Marks: +1, -0

The value of √(144) + √(0.0324) - √(6.76) =

Solution:

Concept:

Square root of perfect squares simplifies directly to their positive base values.

Explanation:

Given:

\sqrt{144} + \sqrt{0.0324} - \sqrt{6.76}

Rewrite each term as a square:

\sqrt{144} = \sqrt{12^2} = 12

\sqrt{0.0324} = \sqrt{(0.18)^2} = 0.18

\sqrt{6.76} = \sqrt{(2.6)^2} = 2.6

Now substitute the values:

12 + 0.18 - 2.6

= 12.18 - 2.6

= 9.58

Answer:

9.58
