Which equation shows a valid, practical step in solving

lesantik [10]

For this case we have the following equation:

$\sqrt [4] {2x-8} + \sqrt [4] {2x + 8} = 0$

If we subtract both sides of the equation $\sqrt [4] {2x + 8}$ we have:

$\sqrt [4] {2x-8} = - \sqrt [4] {2x + 8}$

To eliminate the radical we raise both sides of the equation to the fourth power:

$(\sqrt [4] {2x-8}) ^ 4 = (- \sqrt [4] {2x + 8}) ^ 4$

According to a formula widely used by doctors to determine drug dosages, a person's body surface area (BSA) (in meters squared)

Softa [21]

BSA = hw ÷ 60

We have:
h = 184
w = 83

BSA = (184)(83) ÷ 60
BSA = 15272 ÷ 60
BSA = 254.5 (Rounded to one decimal place)
