Question

2√128 simplify showing step by step

Answer 1

First you factor 128 to get two numbers (one has to be a perfect square)$2\sqrt{128} = 2\sqrt{64 * 2}$
You can then break them down into separate square roots like so
$2\sqrt{64 * 2} = 2\sqrt{64}\sqrt{2}$
Then you simplify the root of 64
$2\sqrt{64}\sqrt{2} = 2 * 8\sqrt{2}$
And finally, multiply the 2 by the 8 and you have your final answer
$16\sqrt{2}$
