Simplify the expression (square root)

√45/144

Thanks.

5/6

To simplify the expression √45/144, we can simplify the numerator and the denominator separately.

First, let's simplify the numerator, √45. To do this, we need to find the largest perfect square that can divide 45 without leaving a remainder. In this case, the largest perfect square that can divide 45 is 9 (3^2), as 9 is a factor of 45.

So, we can rewrite √45 as √(9 x 5). Using the property of square roots, this can be written as √9 x √5.

√9 is equal to 3, so we have 3√5.

Next, let's simplify the denominator, 144. Since 144 is a perfect square (12^2), we can rewrite it as 12 x 12.

So, the simplified expression becomes 3√5 / (12 x 12).

Now, we can simplify further by dividing both the numerator and the denominator by the common factor 12.

3√5 / (12 x 12) simplifies to 3√5 / 144.

Thus, the simplified expression is 3√5 / 144.

Thank you for your answer but I was thinking that the answer will be √9.5/12 then 3√5/12 and I do not know what to do with the denominator "12".

I evaluated it according to the way you typed it.

It seems you are taking it as

√(45/144)
which would be √45/√144 = 3√5/12 = √5/4

Can you see why brackets would be essential for that interpretation?

I get it , Thanks for everything

= 3√5/144

= √5/48

Or could be 3√5/4*3 = 6√5.
