x = 8√x square both sides
x^2 = 64x subtract 64x from both sides
x^2 - 64x = 0 factor
x ( x - 64) = 0
Set both factors to 0 and solve for x and x = 0 or x = 64
x + 10 = 7√x square both sides
(x + 10)^2 = 49x
x^2 + 20x + 100 = 49x subtract 49x from both sides
x^2 - 29x + 100 = 0 factor
(x - 25) (x - 4) = 0 set both factors to 0 and solve for x....so
x = 25 and x = 4
