Which statement is true about the sum square root of 50 square root of 18? In symbols, this expression is:

√50 + √18

These two terms can be simplified, as shown below, and then combined:

√50 = 5√2 + 3√2 = √2(5+3) = 8√2.

This is irrational because √2 is irrational.

we have


√(50)+ √(18)

we know that


50=2*5^(2)


18=2*3^(2)

substitute


\sqrt{2*5^(2)}+ \sqrt{2*3^(2)}

Simplify


5√(2)+ 3√(2)

Combine like terms


5√(2)+ 3√(2)=8√(2)

therefore

the answer is the option

it is irrational and equal to 8 square root of 2
