Solving exponents using logarithms
Web1 Exponential Equations & Logarithms 1 1.1 Exponential Equations An exponential equation is an equation like 2x = 16 or 10x = 3.267. The first equation has answer x = 4, but the second equation is much harder to solve. An exponential equation has the general form ax = b, where the base a and the number b are known and we wish to find find the unknown … WebWith logarithms a ".5" means halfway in terms of multiplication, i.e the square root ( 9 .5 means the square root of 9 -- 3 is halfway in terms of multiplication because it's 1 to 3 and 3 to 9). Taking log (500,000) we get …

WebHow to solve exponential equations of all type using multiple methods. Solving equations using logs. Video examples at the bottom of the page. Make use of the one-to-one property of the log if you are unable to express both sides of the equation in terms of the same base. Step 1: Isolate the exponential and then apply the logarithm to both sides. Step 2: Apply … WebAug 8, 2024 · 4. Use the variable rules. When solving log expressions that have variables, apply the rules for combining like terms with exponents. For instance, the expression (loga_3) + (loga_3) + (loga_4) converts to a^3 + a^3 + a^4. Using the rules for like terms with exponents gives the solution 2a^3 + a^ 4.
