Derick solves the problem below.
-3(4n + 2) = -4n + -2 (4n - 6)
after solving, he says that the equation has no solution.
if derick is correct, show how you know.
if derick is incorrect, show how you know and describe the solution to the equation.

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
