WebbIf you have a single logarithm on each side of the equation having the same base, you can set the arguments equal to each other and then solve. The arguments here are the algebraic expressions represented by \color {blue}M M and \color {red}N N. The second type looks like this. WebbThe logarithms can be combined with an identity since the bases are the same: $$\log_{16}(x^4) = 7$$ Remove the logarithm: $$x^4 = 16^7$$ Take the \(4\)th root of …
WebbSimultaneous equations are two or more equations which are true for two or more unknowns. For example, x + y = 4 and x - 2y = 1 are simultaneous equations which are true for x = 3 and y = 1. When there are two unknowns, as there are here (x and y), then two equations are needed to find the unknowns. WebbLogs can be used to solve algebraic equations where the unknown variable appears as a power An Example : Find the value of x 200(1.1)x = 20000 Simplify divide across by 200 x = 100 1. to find x, rewrite equation so that it is no longer a power Ö …
