Question

How do I solve this type of problem?
The square root of 56 over the square root of 50?

Answer 1

Break down 56 and 50 to prime numbers.

Answer 2

And remember that:
\[\sqrt{x \times x} = \sqrt{x} \times \sqrt{x}\]

Answer 3

ok @ankh then what?

Answer 4

Then you can reduce the expression, because you will have things that will repeat in the nominator and in the denominator

Answer 5

Another important rule:
\[\sqrt{x} \times \sqrt{x} = x\]

Answer 6

ok so now I have 28 over 25 in a square root

Answer 7

A radical times a radical cancels out a radical? @ankh

Answer 8

Yup.

Answer 9

28 and 25? Make sure you do a complete prime factorization

Answer 10
