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 1

Evaluate Log₂6.4 - Log₂10 + Log₂200

Solution

= Log₂6.4 - Log₂10 + Log₂200

= Log₂(6.4x200)

= Log₂(1280)

= Log₂(128)

= Log₂2⁷)

= 7Log₂2

= 7 x 1

= 7

Hence Log₂6.4 - Log₂10 + Log₂200 = 7

TRY THIS…………………….

Evaluate Log₂1.6 - Log₂20 + Log₂ 3200
