What is the solution of (picture) ?

( 8x - 8)^3/2 = 64

√(8x - 8)^3 = 64

(8x - 8)^3 = 4096

8x - 8 = 16

8x = 16 + 8

8x = 24

X= 3

So, the answer is X= 3

i can answer this question sweetie!

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
