WebBy definition, a log a x = x, as log a x is the unique number b such that a b = x. Thus the equation is simply 2 k = 9. I wouldn't use the longer way of writing the equation as 3 log 3 ( 2 k) = 3 2, from which we can infer log 3 ( 2 k) = 2 and therefore 2 k = 9 by definition of logarithm.

WebHow To: Given an equation in logarithmic form logb(x) =y l o g b ( x) = y, convert it to exponential form Examine the equation y = logbx y = l o g b x and identify b, y, and x. Rewrite logbx =y l o g b x = y as by = x b y = x. … WebSolve: $$ 4^{x+1} = 4^9 $$ Step 1. Ignore the bases, and simply set the exponents equal to each other $$ x + 1 = 9 $$ Step 2. Solve for the variable $$ x = 9 - 1 \\ x = \fbox { 8 } $$ Check . We can verify that our answer is correct by substituting our … WebApr 9, 2024 · By using the rules of exponents, we can solve several exponential equations and rewrite each side with the same base as power. Then we use the fact that exponential functions are individually to compare the exponents and solve the unknown. If an exponential equation with a shared base cannot be rewritten, overcome by using each … how heavy is a bear pelt
