After solving an exponential equation, check each solution in the original equation to find and eliminate any extraneous solutions. When given an equation of the formlogb(S)=clogb(S)=c, whereSis an algebraic expression, we can use the definition of a logarithm to rewrite the equation as the...
How To: Given an equation in logarithmic form logb(x)=ylogb(x)=y, convert it to exponential form. Examine the equation y=logbxy=logbx and identify b, y, and x. Rewrite logbx=ylogbx=y as by=xby=x.Think About It Can we take the logarithm of a negative number? Re-read the ...
– 4 = 0 & (x-4)(x+1) = 0 & x=4 and x = -1 Exponentials of Unequal Bases Exponentials of Unequal Bases • Use logarithm (inverse function) of same base on both sides of equation Solve: e x = 72 e x = 72 log e log e x = ln 72 4.277 Solve: 7 x-1 = 12 7 x-...
To solve an exponential equation, logarithms of both sides of the equation are taken and converted to the equivalent exponential form to solve a logarithmic equation. Exponential functions occur in a wide variety of applied problems. This chapter presents problems dealing with population growth such ...
Answer to: Write the exponential equation in logarithmic form. e^{-0.9}=0.406 By signing up, you'll get thousands of step-by-step solutions to your...
Logarithmic equationsare equations which incorporate logarithms. Alogarithmis a function which is the inverse of taking a number to a power. This means that {eq}\log_b a {/eq} is the inverse of {eq}b^a {/eq}. Logarithms only take in positive numbers as a value. Given the equation {...
1) Logarithmic Model Equation 对数模型方程例句>> 2) exponential equation model 指数方程模型 1. In contrast to exponential equation model based on regression method, it is considered a new method for erecting exponential model. 无偏GM(1,1)模型是在传统GM(1,1)模型基础上的一种改进,它实际上是...
Given exponential equation: 3x – 3x+2 By using the property: ax ay = ax+y Hence, 3x+2 can be written as 3x.32 Thus the given equation is written as: 3x – 3x+2 = 3x – 3x·9 Now, factor out the term 3x : 3x – 3x+2 = 3x – 3x·9 = 3x(1 – 9) ...
Assume an exponential equation in its general form am=b. We change it to the logarithmic equation as shown: loga(b)=m Because the exponential and logarithmic functions are reversed by each other.Answer and Explanation: The given exponential equation is: 3x=14 Recall that if the general ...
