Q. Solve the exponential equation for x.24x−5⋅32x+1=26x−7x=□
Write Equation: Write down the given exponential equation and simplify the bases to have the same base.The given equation is:24x−5×32x+1=26x−7We know that 32 is 25, so we can rewrite 32x+1 as (25)x+1.
Apply Power Rule: Apply the power of a power rule to simplify the equation.Using the power of a power rule (ab)c=ab∗c, we get:24x−5×(25)x+1=26x−724x−5×25x+5=26x−7
Combine Terms: Combine the terms with the same base on the left side of the equation using the property of exponents that states am⋅an=am+n. 24x−5+5x+5=26x−729x=26x−7
Set Exponents Equal: Since the bases are the same, we can set the exponents equal to each other and solve for x.9x=6x−7
Subtract and Isolate: Subtract 6x from both sides to isolate the variable on one side.9x−6x=6x−6x−73x=−7
Divide and Solve: Divide both sides by 3 to solve for x.33x=3−7x=3−7
