Question

1 - Simplify :3√2+√8-√50 Ans:

​

Answer 1

Answer:

0

Step-by-step explanation:

Take the problem into two.

3√2       and            8√50

Now leave 3√2 as its already simplified.

Now, extract the second number fully into factors which brings you.

√2 * 2 * 2   -   √2 * 5 * 5

As there is 2 * 2 = 2² in the first term and 5 * 5 = 5² in the second term. Bring them both outside which gives you

2√2 - 5√2

-3√2                                                    (a√b - c√b = a - c√b)

So, lets go to solving the real problem

3√2 + - 3√2

0                             (a√b + c√b = a + c√b)
