Question

If x -√2=√8, then what is the value of x?

Answer 1

Answer:

x  = 3$\sqrt{2}$

step-by step:

x -√2=√8

x = $\sqrt{12}$

x = $\sqrt{6 * 2}$

x = $\sqrt{2 * 2 * 3}$

x  = 3$\sqrt{2}$

Answer 2

Answer:

x = 3 sqrt(2)

Step-by-step explanation:

x -√2=√8

Add sqrt(2) to each side

x - sqrt(2) + sqrt(2) = sqrt(8)+ sqrt(2)

x = sqrt(8)+ sqrt(2)

Rewriting sqrt(8)  as sqrt(4) sqrt(2) = 2 sqrt(2)

x = 2 sqrt(2)+ sqrt(2)

x = 3 sqrt(2)
