$\log \left(4x^2\right)=\log \left(10^{128}\right)$
Learn how to solve logarithmic equations problems step by step online. Solve the logarithmic equation log(4*x^2)=128. Express the numbers in the equation as logarithms of base 10. For two logarithms of the same base to be equal, their arguments must be equal. In other words, if \log(a)=\log(b) then a must equal b. Divide both sides of the equation by 4. Removing the variable's exponent.
