Question

value of √144+√400-√225 will​

Answer 1

Answer:

12 + 20 + 25

7

Step-by-step explanation:

Answer 2

$\longrightarrow{\green{}}$ $\sqrt{144} + \sqrt{400} - \sqrt{225}$

$\longrightarrow{\green{}}$ $\sqrt{12 \times 12} + \sqrt{20 \times 20} - \sqrt{15 \times 15}$

$\longrightarrow{\green{}}$ $\sqrt{ ({12})^{2} } + \sqrt{ ({20})^{2} } - \sqrt{ ({15})^{2} }$

$\longrightarrow{\green{}}$ $12 + 20 - 15$

$\longrightarrow{\green{}}$ $32 - 15$

$\longrightarrow{\green{}}$ $17$

Note:

$\sqrt{ ({a})^{2} } = a$
