If the base is a number followed by zeros we only have to raise the number to the exponent and then put as many zeros as we need. Since 100 has 2 zeros we have to write two zeros as many times as the exponent indicates.ġ00 2→ Since the exponent is 2 we have to write 2 zeros twice:ġ00 4→ Since the exponent is 4 we have to write 2 zeros four times:įor any base with more zeros we should carry out the same procedure: take note of the number of zeros in the base and repeat that number of zeros as many times as the number that there is in the exponent. The exponent indicates how many zeros we should put after the result.ġ0 2 → Since the exponent is 2 we have to put 2 zeros: 10 2 = 100ġ0 5 → Since the exponent is 5 we have to put 5 zeros: 10 5 = 100 ,000 Powers of base 100 We know that 10 5 has five factors that are 10 and 10 2 has two factors that are 10. To put this multiplication in the form of powers we first write the 4 and then above and to the right we write a small number 5. In this lesson, we developed a rule for multiplying powers of 10: multiplying powers of 10 corresponds to adding the exponents together. We are multiplying the number 4 a total of 5 times. This math game is a fun way help fifth graders build their number sense while boosting their confidence working with exponents. There is a slight trick to it, but it's still pretty easy, huh To represent 10 to a negative power. In Jumpy: Powers of 10, players need to correctly choose the exponent that represents a given number, such as 100, 1,000, and 100,000, in order to get Roly across the river. Now, here is the great thing about powers of 10. Remember that powers serve to allow us to write a multiplication problem of the same number several times in a simpler way. Multiply and Divide by Powers of 10 Subject: Mathematics Age range: 11-14 Resource type: Other 16 reviews File previews ppt, 2.98 MB A mini whiteboard exercise which can be used to determine students prior knowledge or can be used as an end of topic assessment on multiplying and dividing by powers of 10. How to Multiply by Powers of 10 Using the Exponent in Powers of 10. In this post, we are going to learn how to raise numbers to powers when the base is composed of zeros.
