Answer:Simplifying
x = -2.125
Step-by-step explanation:Add '-10' to each side of the equation.
10 + -10 + 8x = -7 + -10
Combine like terms: 10 + -10 = 0
0 + 8x = -7 + -10
8x = -7 + -10
Combine like terms: -7 + -10 = -17
8x = -17
Divide each side by '8'.
x = -2.125
Simplifying
x = -2.125
LOL...it took me a few seconds to realize what you were attempting to express...which is the fifth root of 13 cubed...
(13^3)^(1/5) rule: (a^b)^c=a^(b*c)
13^(3*1/5)
13^(3/5)
The answer is 6 square root of 3.
4 times 12 square rooted minus 2 times square root of 3 = 10.39230485 =
6 square root of 3.
