The square roots of 75 are $5\sqrt{3}$ and $-5\sqrt{3}$
Steps to Solve
- Identify the positive square root
The positive square root of 75 is given by the positive solution to the equation $\sqrt{75}$.
- Simplify under the radical
We can simplify the square root by finding the prime factorization of 75: $75 = 3 \times 25 = 3 \times 5^2$. So the square root can be simplified as follows:
$$\sqrt{75} = \sqrt{3 \times 5^2} = 5 \sqrt{3}$$
- Consider both positive and negative roots
Remember that every positive number has two square roots: one positive and one negative. Hence, the square roots of 75 are:
The positive root is $5 \sqrt{3}$, and the negative root is $-5 \sqrt{3}$.
The square roots of 75 are $5\sqrt{3}$ and $-5\sqrt{3}$
