Answer for screen readers
The simplified radical form of the square root of 75 is $5\sqrt{3}$.
Steps to Solve
-
Factor 75 into its prime components First, identify the prime factors of 75. We can do this by dividing by the smallest prime numbers: $$ 75 = 3 \times 25 $$ Next, factor 25 further: $$ 25 = 5 \times 5 $$ So, the complete factorization of 75 is: $$ 75 = 3 \times 5^2 $$
-
Apply the square root to the factors Now we can express the square root of 75 using the prime factors: $$ \sqrt{75} = \sqrt{3 \times 5^2} $$
-
Simplify using properties of square roots We can separate the square root and simplify: $$ \sqrt{75} = \sqrt{3} \times \sqrt{5^2} $$ Since the square root of $5^2$ is 5, we then have: $$ \sqrt{75} = \sqrt{3} \times 5 $$
-
Write the final simplified form Rearranging gives us: $$ \sqrt{75} = 5\sqrt{3} $$
The simplified radical form of the square root of 75 is $5\sqrt{3}$.
More Information
The square root of 75 can be simplified by breaking it down to its prime factors, which allows us to express it in a more manageable form. Understanding how to simplify square roots is a useful skill in algebra and number theory.
Tips
