$\quad : \implies\sf{\dfrac{\sqrt{1.21} + \sqrt{0.81}}{{\sqrt{3.61} - \sqrt{2.89}}}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\dfrac{\sqrt{1.1\times 1.1} + \sqrt{0.9\times 0.9}}{{\sqrt{1.9 \times 1.9} - \sqrt{1.7 \times 1.7}}}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\dfrac{{1.1} + {0.9}}{{{1.9} - {1.7}}}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\dfrac{2}{0.2}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\dfrac{2\times 10}{0.2 \times 10}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\dfrac{20}{2}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies\sf{\cancel{\dfrac{20}{2}}}$

$\begin{gathered} \\ \end{gathered}$

$\quad : \implies{\sf{10}}$

Square Root

• ● In math, squares and square roots are inverse operations. The Square of a number is the value of power 2 of the number, while the square root of a number is the number that we need to multiply by itself to get the original number. If a is the square root of b, it means that a×a=b. The square of any number is always a positive number, so every number has two square roots, one positive value, and one negative value.
• ● For example, both 2 and -2 are square roots of 4. But at most places, you will find that only the positive value is written as the square root.
