whats grater -√45 or 3√27

Answer 1

To compare -√45 and 3√27, we need to simplify both expressions.

√45 = √(9 * 5) = 3√5
3√27 = 3√(9 * 3) = 3 * 3√3 = 9√3

Now we can compare:

3√5 or 9√3

Since √5 ≈ 2.236 and √3 ≈ 1.732, we can approximate:

3 * 2.236 ≈ 6.708 or 9 * 1.732 ≈ 15.588

Therefore, 3√5 is greater than 9√3.
