2*sqrt(27) - sqrt(3) = 2*sqrt(9*3) - sqrt(3) = 2*sqrt(9)*sqrt(3) - sqrt(3)
= 2*3*sqrt(3) - sqrt(3) - 6*sqrt(3) - srt(3) = 5*sqrt(3)

Can two irrational numbers have a product as rational?
Yes. A simple example: sqrt(2)*sqrt(2) = 2 This property is used to "simplify" (rationalise the denominator of) surds.
What is x when 13x plus 27 equals 3x plus 32?
13x+27=3x+32 Reorder 13x-3x=32-27 Simplify 10x=5 Simplify x=5/10 Simplify x=1/2 Answer
What is the simplest form of 27 over 54?

How do you work out surds?
Surds are normally irrational numbers but they can be simplified for instance the square root of 12 can be expressed as 2 times the square root of 3
What number multiplied by what number gives the product of negative 72 and sum of negative 4?
The numbers are: -2 +2*sq rt 19 and -2 -2*sq rt 19 Check: (-2 +2*sq rt 19)*(-2 -2*sq rt 19) = -72 and (-2 +2*sq rt 19)+(-2 -2*sq rt 19) = -4

How do you simplify 27 over 18?
27/18=3/2. Find the largest number that both numbers can be divided by. In this case, it is 9 (27/9=3 and 18/9=2) and in the case 18, it would be 2. So, 3/2 is the answer. Was this helpful?
