An expression is shown below:

the square root of 18 + the square root of 2

Which statement is true about the expression?

A:it is rational and equal to 3
B:it is rational and equal to 4
C:it is irrational and equal to 3 times the square root of 2
D:it is irrational and equal to 4 times the square root of 2

Respuesta :

Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.

If we solve it
 
sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)

D :D
