MATHEMATICS PROBLEM SOLVER

It is a site for parents, students and teachers. This site can help O-LEVEL or GCSE secondary school students in mastering mathematics subject. It intends to involve the learners by making them follow up the examples before they can do questions on their own at the TRY THIS.... section. There are some videos, tests, quizzes and past examination questions. Learning the examples will ultimately give students the required confidence in solving various questions in mathematics.

LOGARITHMS 4

If Log_ax = ¹/₂Log_a144+ ¹/₃ Log_a125 find x.

Solution

Log_ax = ¹/₂Log_a144+ ¹/₃ Log_a125

Log_ax = Log_a144^1/2 + Log_a125^1/3 [Square root of 144 is 12, Cube root of 125 is 5]

Log_ax = Log_a12+ Log_a5

Log_ax = Log_a(12 x 5)[Since Log_am+ Log_an = Log_amn]

~~Log~~_ax = ~~Log~~_a60

x = 60

TRY THIS………………

If Log_ax = ¹/₃Log_a216+ ¹/₄ Log_a81; find x.
