Which of the following is true regarding the solutions to the logarithmic equation below?
2log3(x) - 4
log2 (x²)-4
x² - 34
x? - 81
-x-9.-9
ox-9 and x = -9 are true solutions
x-9 and x = -9 are extraneous solutions
o x-9 is an extraneous solution and x=-9 is a true solution
x-9 is a true solution and x = -9 is an extraneous solution

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.
