Level 1 Level 2 Level 3 Level 4 Exam-Style Game Description Help More Indices

Arrange the given statements involving indices to show whether they are true or false.

TRUE

FALSE

$(x^3)^4 \equiv x^7$

$\frac{x^6}{x^3} \equiv x^2$

$x^8 \div x^4 \equiv x^2$

$x^2 \times x^3 \equiv x^6$

$(x^3)^4 \equiv x^{12}$

$\frac{x^7}{x^3} \equiv x^4$

$x^8 \div x^5 \equiv x^3$

$x^2 \times x^3 \equiv x^5$

Your answer is not correct. Try again.

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College:

"Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work"

Comment recorded on the 1 August 'Starter of the Day' page by Peter Wright, St Joseph's College:

"Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities.
Thanks for such a great resource!"

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths main page links to more activities designed for students in upper Secondary/High school.
