O level Indices and Logarithm Quiz 1

15 Questions

Quiz Description

In this quiz, we shall be revising indices and logarithms with questions that have been set based on the national curriculum for the gce ordinary level. The topics indices and logarithms are the basics of mathematics as principles and laws from indices and logarithm are applied in so many other aspects of mathematics and not just mathematics, Physics, chemistry and other subjects too. Here, we are going to cover the basics of this topic using questions.

Indices (Sometimes-called powers) are notations used to shorthand expressions involving numbers multiplied by themselves a number of times whereas Logarithm is the exponent or power to which a base must be raised to yield a given number.
