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 17

Evaluate Log₂16 - Log₂100 + Log₂40

Solution

= Log₂16 - Log₂100 + Log₂40

= Log₂(16x50)

100

= Log₂(800)

100

= Log₂(8)

= Log₂2³

= 3Log₂2

= 3 x 1

= 3

Hence Log₂16 - Log₂100 + Log₂40 = 3

TRY THIS…………………….
