Q. Solve the exponential equation for x.259−x54x+3=52x+5x=□
Recognize and simplify the equation: Simplify the equation by recognizing that 25 is a power of 5.Since 25=52, we can rewrite 259−x as (52)9−x.This gives us 54x+3/52(9−x)=52x+5.
Apply properties of exponents: Apply the properties of exponents to simplify the equation further.Using the property am−n=am/an, we can combine the exponents on the left side of the equation.This gives us 54x+3−2(9−x)=52x+5.
Simplify the exponent: Simplify the exponent on the left side of the equation.Calculate 4x+3−2(9−x) which simplifies to 4x+3−18+2x.This simplifies further to 6x−15.Now we have 56x−15=52x+5.
Set the exponents equal: Since the bases are the same and the equation is an equality, we can set the exponents equal to each other.This gives us 6x−15=2x+5.
Solve the linear equation: Solve the linear equation for x.Subtract 2x from both sides to get 4x−15=5.Then add 15 to both sides to get 4x=20.Finally, divide both sides by 4 to find x=5.
