✪QUESTION✪:-

Find the difference $\sqrt{32} -\sqrt{18}$

✪ANSWER✪:-

➥$\sqrt{32} = \sqrt{2 \times 2 \times 2 \times 2 \times 2}$

➥$\sqrt{32} = 2 \times 2 \sqrt{2}$

➥$\sqrt{32} = 4 \sqrt{2}$

➥$\sqrt{18} = \sqrt{2 \times 3 \times 3}$

➥$\sqrt{18} = 3 \sqrt{2}$

☞$\sqrt{32} - \sqrt{18} = 4 \sqrt{2} - 3 \sqrt{2}$

☞$\sqrt{32} - \sqrt{18} = \sqrt{2}$
