Answer 2

To simplify the given expression √(-25)^2-√27/√3-√2*√18, let's break it down step by step:

1. √(-25)^2: This is equivalent to √25, as squaring a number eliminates the negative sign. The square root of 25 is 5.

2. √27/√3: To simplify this, we can rationalize the denominator by multiplying both the numerator and denominator by √3. This gives us (√27 * √3) / (√3 * √3), which simplifies to √(273) / 3. √(273) is √81, which is equal to 9. So the expression becomes 9/3, which simplifies to 3.

3. √2*√18: This can be simplified by multiplying the numbers inside the square roots. √2 * √18 is equal to √(2 * 18), which simplifies to √36. The square root of 36 is 6.

Now let's substitute these simplified values back into the original expression:

√(-25)^2 - √27/√3 - √2*√18 = 5 - 3 - 6 = -4

Therefore, the simplified value of the expression is -4.
