Step-by-step explanation:
We know that,
√28 = √(2 × 2 × 7)
= √(4 × 7)
= √4 × √7
= 2 × √7
= 2√7
then,
2√28 = 2(2√7)
= 4√7
Now back to our Question,
(2√28) ÷ √7
= (4√7) ÷ √7
Thus, cancelling the equal terms we get,
= 4
You just had to simplify the square root, next time try it yourself and then help others, See you around Champion.
Hope it helped and you understood it........All the best
