Question

simplify √72+√800-√162

Answer 1

Hey User ✌

Here's your answer friend,

************************************************************************

==> √72 = √2³ X √3²

==> √72 = √2² X √3² X √2

==> √72 = 2 X 3 √2

==> √72 = 6√2

and

√800 = √2^5 X √5²

==> √800 = √2² X √2² X √5² X √2

==> √800 = 2 X 2 X 5√2

==> √800 = 20√2

and now,

√162 = √9² X √2

==> √162 = 9√2

Now, Simplifying

==> √72 + √800 - √162

==> 6√2 + 20√2 - 9√2 .........{From above}

==> 26√2 - 9√2

==> 17√2

HOPE IT HELPS YOU ^_^
