Laws of Indices - True or False?

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

Arrange the given statements 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?

"Thanks very much for this one. We developed it into a whole lesson and I borrowed some hats from the drama department to add to the fun!"

Comment recorded on the 16 March 'Starter of the Day' page by Mrs A Milton, Ysgol Ardudwy:

"I have used your starters for 3 years now and would not have a lesson without one! Fantastic way to engage the pupils at the start of a lesson."

Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing.

Featured Activity

Where's Wallaby?

Find the hidden wallaby using the clues revealed at the chosen coordinates. Not only is this a fun way to practise using coordinates it is also a great introduction to Pythagoras' theorem and loci.

Numeracy

"Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

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.

Curriculum Reference

See the National Curriculum page for links to related online activities and resources.

Examples

\( 5^a \times 5^b \equiv 5^{a+b} \)

\( 5^a \div 5^b \equiv 5^{a-b} \)

\( (5^a)^b \equiv 5^{ab} \)

\( 5^1 \equiv 5 \)

\( 5^0 \equiv 1 \)

\( 5^{-1} \equiv \frac15 \)

\( 5^{-2} \equiv \frac{1}{25} \)

\( 5^{\frac12} \equiv \sqrt{5} \)

\( 5^{\frac13} \equiv \sqrt[3]{5} \)

\( 5^{\frac23} \equiv \sqrt[3]{5^2} \)
