Raise to Power of 4/3: Now, raise both sides of the equation to the power of 4/3 to get rid of the exponent on the left side.((x2−x−51)3/4)4/3=274/3x2−x−51=274/3
Calculate 2734: Calculate 2734. Since 27 is 33, this simplifies to (33)34.2734=(33)34=33∗34=342734=81
Substitute 81: Substitute 81 back into the equation.x2−x−51=81
Solve for x: Now, let's solve for x by moving 81 to the left side of the equation.x2−x−51−81=0x2−x−132=0
Factor the Quadratic: Factor the quadratic equation.(x−12)(x+11)=0
Set Equal and Solve: Set each factor equal to zero and solve for x.x−12=0 or x+11=0x=12 or x=−11
