Describe each step taken to solve the equation. Then, check the solution to see if it is valid. If it is not a valid solution, explain why a) √x+6=4b)∛x+6=4.
Accepted Solution
A:
Answer:Step-by-step explanation:given,a) √x + 6 = 4 to solve the above equation subtract both side with 6 √x + 6 - 6 = 4 - 6 √x = -2 squaring both side (√x)² = (-2)² x = 4 a) ∛x + 6 = 4 to solve the above equation subtract both side with 6 ∛x + 6 - 6 = 4 - 6 ∛x = -2cubing both side (√x)³ = (-2)³ x = -8
