I need to know what this answer is<br><br><br>3. Write the expression 175 using radicals. ​
Rus_ich [418]

Answer:

5√7

Step-by-step explanation:

What we want to do is first just put the 175 in a sqrt like this:

√175

Next we do prime factorisation to try and simplify further.

         175

      /          \

   25            7

  /     \

5         5

We can figure out that this out √5^2 times 7

we can cancel the sqrt and the squared and simplify to 5√7

So there is your answer, 5√7.

If you have any questions feel free to ask. Also for the prime factorisation the formatting may be off, sorry for the inconvenience and have a good day!
