Thus, 9^m = (3^2)^m = 3^ (2m) 81=3^4. Now your equation can be written as: 3^ (2m-1)*3^ (2m)=3^4. The left side can be simplified further by using properties of exponents: to multiply values with a common base, we add the exponents. 3^ (2m-1+2m)=3^4. 3^ (4m …
WebWe can solve equations in which a variable is raised to a rational exponent by raising both sides of the equation to the reciprocal of the exponent. The reason we raise the equation to the reciprocal of the exponent is because we want to eliminate the exponent on the variable term, and a number multiplied by its reciprocal equals 1. WebWhen it’s not convenient to rewrite each side of an exponential equation so that it has the same base, you do the following: Take the log (or ln) of both sides Apply power property Solve for the variable Example: Solve for x. a) 6 x = 42 b) 7 x = 20 c) 8 2x - 5 = 5 x + 1 d) 3 x = 5 x - 1 Show Video Lesson
