simplify: square root of 5 + square root of 20 - square root of 27 + square root of 147. simplify: 6/4square root of 2 sqrt 5 + sqrt 20 - sqrt 27 + sqrt 147 = sqrt 5 + sqrt (4*5) - sqrt (3*9) + sqrt (49*3) = 3 sqrt 5 - 3 sqrt 3 + 7 sqrt 3 = 3 sqrt 5 + 4

The expression x^2-7 is not factorable using integer values. But the expression can be written in the form X^2-(Square root7)^2 enabling us to factor it as a “binomial” and its conjugate: (x+square root 7)(x-square root 7) Use this idea to factor the
