Q. Find the PRODUCT of the solutions to2(x+2)4−6=156A) −5B) 2C) −2D) 3
Simplify Equation: Simplify the equation to isolate the term with the exponent.We start by adding 6 to both sides of the equation to get:2(x+2)4=162Now, divide both sides by 2 to isolate the term with the exponent:(x+2)4=81
Take Fourth Root: Take the fourth root of both sides to solve for x.Since (x+2)4=81, we can take the fourth root of both sides to get:x+2=±3Because the fourth root of 81 is 3, and we consider both the positive and negative roots.
Solve for x: Solve for x.We have two possible solutions for x+2:x+2=3 and x+2=−3For x+2=3, subtract 2 from both sides to get x=1.For x+2=−3, subtract 2 from both sides to get x=−5.
Find Product: Find the product of the solutions.The solutions are x=1 and x=−5. To find the product of the solutions, we multiply them together:Product = 1×(−5)=−5
