Asked by Andrea
Count Iblis what is the answer to 2 square root sign 18x? The instructions say to simplify or reduce.
2*(18x)<sup>1/2</sup>=
2*(9*2)<sup>1/2</sup>=
2*3(2)<sup>1/2</sup>=
6*(2)<sup>1/2</sup>
If you can leave it in this form, the above is the way to end. If you are to continue to a final answer, then, finish by 6*1.414 =8.485.
6*(2)<sup>1/2</sup> is an exact answer.
8.485 is not exact because square root 2 is not an even number.
