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.

Evaluate Log100 - log0.001 - log0.0001

Solution

= Log100 - log0.001 - log0.0001

= Log10² - log10^-3 – log 10^-4

= 2Log10 - (-3 log10) – (-4log 10)

= (2x1) - (-3x1) - (-8x1)

=2 - (-3) – (-4)

= 2 + 3 + 4

Hence Log100 - log0.001- log0.0001 = 9
