Q. Solve the exponential equation for x.323x=8x−12x=□
Recognize Powers of 2: Recognize that both 32 and 8 are powers of 2.32=25 and 8=23.Rewrite the equation using this fact.323x=(25)3x and 8x−12=(23)x−12.
Apply Power Rule: Apply the power of a power rule to simplify the exponents.(25)3x=235x and (23)x−12=23(x−12).Now the equation is 235x=23(x−12).
Set Exponents Equal: Since the bases are the same, set the exponents equal to each other.35x=3(x−12).
Solve for x: Solve for x by first distributing the 3 on the right side of the equation.35x=3x−36.
Clear Fraction: Multiply every term by 3 to clear the fraction.5x=9x−108.
Move Terms: Move all x terms to one side and constants to the other side.5x−9x=−108.
Combine Like Terms: Combine like terms.−4x=−108.
Divide by −4: Divide both sides by −4 to solve for x.x=−4−108.
Calculate x: Calculate the value of x.x=27.
