Lesson 5: Powers of ten

# Introduction to powers of 10

Exponents are a way of simplifying the notation for repeated multiplication. When using a base of 10, the exponent tells you how many times to multiply 10 by itself. Converting between exponential notation and standard notation is straightforward: for example, 10 to the second power is the same as 10 times 10, or 100.

• For the confused people, I'll give an example. Let's say you have 10 to the 4th power. you would add 4 zeros after the 1, giving you 10,000. The same thing goes for when you use different powers.
Ex: 10 to the 2nd power, 10 to the 3rd power, 10 to the 5th power, etc. etc
Even when you use numbers other than 10, this still applies.
• You are right about ten, but 2^2=20 isn't correct.
• From and beyond it made no sense to me but okay
• why dont u have a father?
• its cuz he left to get the milk
• So if I were to do 10 to the power of 15 I would add 15 zeros, right?
• That is correct. But you have to make sure you are adding the zeroes to the first digit, one, or else your number may be 10 times too high.
• Let me make this easy for yall... First, you look at the little number above the big number. for example, ten to the power of six. you add six zeros to get the answer. or you can do it the hard way. your choice! but my teacher taught us the eeeeaaaassssyyyy way!
P.S. not da baby... DUCKBABY
• Is there a 10 to the -1 power?
• 10 to -1 power is equal to 1/10 when you have a negative exponent you always make it a fraction. For example 5 to the -1 power is equal to 1/5.
Hopes this helps:) And sorry for being 1 year late.
• Is he trying to do the power of ten you need to times 10×10×10=1,000 not 100 that answer is wrong because 10×10=100? The hat is BOB BBC.
• Ex:
10x10=100 100=10 to the second pattern. It's the same thing for each power of 10.Hope this helps anyone struggling. Tell me ay feedback if I explained wrong. Thanks in advance.
• We already know that this is easy
• It is quite easy to calculate once you know the basic formula. However, it may be hard to understand for some people and it can become very difficult later on, when you move from powers of ten to powers of other numbers with more or more complicated digits, like... let's say... 101190 to the 23d power

just saying google = 100 zero's
