Identify Equation and Base: Identify the given equation and the base of the logarithm.The equation is x2−log4(x)=π, and the base of the logarithm is 4.
Rewrite Logarithmic Term: Rewrite the logarithmic term using the property of exponents: aloga(b)=b. Here, we can write xlog4(x) as 4 because 4 is the base of the logarithm.
Combine Exponents: Apply the property of exponents to combine the terms with the same base. x2×x−log4(x)=x2−log4(x).
Substitute Rewritten Term: Substitute the rewritten logarithmic term back into the equation. x2⋅4−1=π.
Recognize Reciprocal: Recognize that 4−1 is the reciprocal of 4, which is 41. x2⋅(41)=π.
Isolate x2: Multiply both sides of the equation by 4 to isolate x2 on one side.4×(x2×(41))=4×π.
Take Square Root: Simplify the equation by canceling out the 41 on the left side.x2=4×π.
Calculate Square Root: Take the square root of both sides to solve for x.x=4⋅π.
Simplify Square Root: Calculate the square root of 4×π. x=4×π.
Rewrite Using Exponents: Simplify the square root of 4, which is 2.x=2×π.
Change of Base Formula: Rewrite the equation using the property of exponents: x(a−b)=xbxa.x(2−log4(x))=x(log4(x))x2.
Simplify Expression: Recognize that xlog4(x) can be rewritten using the change of base formula for logarithms: log4(x)=log(4)log(x).x2−log4(x)=4log4(x)x2.
Cancel Out x: Simplify the expression using the property aloga(b)=b. x2−log4(x)=xx2.
Set Equal to pi: Simplify the right side of the equation by canceling out one x.x2−log4(x)=x.
Set Equal to pi: Simplify the right side of the equation by canceling out one x.x2−log4(x)=x.Set the simplified expression equal to π.x=π.
