Question

5y +1/5y=?????????????​

Answer 1

Answer:

Here is your answer may this helps you.

Answer 2

Step-by-step explanation:

5y + 1/5y =6

Squaring both sides

(5y + 1/5y)²=6²

a²+b²+2ab

(5y)²+(1/5y)²+2 into 5y into 1/5y =(6)²

(25y²+1/25y²)+2 =36

25y²+1/25y²= 36–2

25y²+1/25y²=34

Subracting 2 from both sides

25y²+1/25y²-2 = 34–2

(5y)²+1/5y²) -2 =32

It include the identity :

a²+b²-2ab = (a-b)²

(5y - 1/5y )² = 32

5y - 1/5y = 32 under square root

=under square root 2×2×2×2×2

One two is not in pair

Hence the answer is 4under root 2
