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.


calculista

we have

[tex]\sqrt{50}+ \sqrt{18}[/tex]

we know that

[tex]50=2*5^{2}[/tex]

[tex]18=2*3^{2}[/tex]

substitute

[tex]\sqrt{2*5^{2}}+ \sqrt{2*3^{2}}[/tex]

Simplify

[tex]5\sqrt{2}+ 3\sqrt{2}[/tex]

Combine like terms

[tex]5\sqrt{2}+ 3\sqrt{2}=8\sqrt{2}[/tex]

therefore

the answer is the option

it is irrational and equal to 8 square root of 2
