$2 | b | \sqrt{2}$ $2|b|sqrt2$

$\sqrt{8 b^{2}}$ $sqrt(8b^2)$

Using the properties of radicals, try to remove perfect squares:
$\sqrt{2 \cdot 4 \cdot b^{2}} =$ $sqrt(2*4*b^2)=$
$2 | b | \sqrt{2}$ $2|b|sqrt2$

Remember absolute value when taking take an even root, and the result has an odd exponent
