Which of the following shows the true solution to the logarithmic equation solved below? log Subscript 2 Baseline (x) = log Subscript 2 Baseline (x + 7) = 3. log Subscript 2 Baseline left-bracket x (x + 7) right-bracket = 3. x (x + 7) = 2 cubed. x squared + 7 x minus 8 = 0. (x + 8) (x + 1) = 0. x = negative 8, 1

The solution of the system of linear equations is b. (2,-3) because the solution is the poi (point of intersection)

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.
