Question

2√28÷√7 it's answer is 4 but I don't know how to do this question​

Answer 1

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
