Answer:
Step-by-step explanation:
27 = 3 * 3 * 3
-3√27 = -3*3√3 = -9√3
Index of the radical is 2. So, after prime factoring, for each two of same number, pull one outside.
-3√45= -3√3*3*5 = -3*3√5 = -9√5
-√18 = -√2*3*3 = -3√2
-3√27 - 2√2 - 3√45 - √18 = -9√3 - 2√2 -9√5 -3√2
Now combine like terms
= -9√3 - 9√5 -2√2 - 3√2
= -9√3 - 9√5 - 5√2
