\frac{1}{\sqrt{2} }  rationalize denominator.

\frac{1}{\sqrt{2}} × \frac{\sqrt{2}}{\sqrt{2} } = \frac{\sqrt{2}}{\sqrt{2} \sqrt{2} }  =  \frac{\sqrt{2} }{\sqrt{4}} =  \frac{\sqrt{2}}{2}

olga55 [171]

Answer:

14\text{ and }16

Step-by-step explanation:

Let the smaller number be x. Since they are consecutive even numbers, the larger number can be represented by x+2.

Therefore, we have the following equation:

8(x+2)-5x=58,\\8x+16-5x=58,\\3x=42,\\x=\boxed{14}

Thus, the larger number is x+2=\boxed{16}
