POWERS

The power of a number shows you how many times to use the number in a multiplication.
It is written as a small number to the right and above the base number.
In this example: 8²= 8 × 8 = 64 (Another name for power is index or exponent)

In words: 8²could be called "8 to the power 2" or "8 to the second power", or simply "8 squared"
See more examples:
Example: 5³= 5x5x5=125 /

• In words: 5³ could be called “5 to the third power”, “5 to the power 3” or simply “ 5 cubed”
  

Exponents make it easier to write and use many multiplications.

• Example: 9⁶ is easier to write and read than 9x9x9x9x9x9
  

NEGATIVE EXPONENTS

A negative exponent means how to many times to divide. For example: 8 raised to -1 = 1/8= 0,125

MATHS

ROUNDING OFF DECIMALS

Rounding off decimals is a technique used to estimate or aproximate values. We can around to any place.ROUND UP AND ROUND DOWN increase one digit or decrease one digit. If the next place beyond where we are terminating the decimal is greater than or equal to five we round up.



How to round down: if the number to the right of our terminating decimal place is four or less.

For example:

a) 3,84 Here we have a decimal number to round off to tenths. First of all if the next place beyond where we are terminating the decimal is less than five we will round down. So if the number is 3,84 we must round down to the eight.

Well that is our first video, we hope that you will enjoy as much as we do, we are back to table, and this is our little presentation. See you guys!
