*wel i guess that's it.. if i'm missing any or made a mistake just leave a comment or something then i'll edit it !! hehehe..by the way ... its due on the 6th of febuary.. i think .. well I need to study ... later people*

*:P have a great weekend :P*

*Anne u better look at dis!! :P*

*well since im on da blog already ill explain some stuff that we learned so far....*

**exponential form**

- a short hand method of writing #'s expressed as repeated multiplication

*example:6 ^{12}*

**expanded form**

- repeated multiplication of a base

example: 3x3x3x3x3x3

**standard form**

- the usual way we write a number

example: 8

**base**

- the number used as a factor for repeated multiplication

*example: 6 ^{12} 6 is da base*

**exponent**

*- the raised number that tells you how many times the base is repeatedly multiplied*

*example: 6 ^{12} 12 is da exponent*

**product law**

- to multiply powers with the same base then add the exponents

*example: (x ^{2})(x^{3})= x^{5}*

**quotient law**

- to divide powers with the same base then subtract the exponents

*example: x ^{4}÷x^{3}= x^{1}*

**reciprocal**

- a reciprocal is a fraction that is flipped upsidedown. we use it when we have a negative exponent

*example: 7 ^{-2} = 1/49*

**power law**

- to raise a power to a power,then multiply the exponents

example: (7^{3})^{2} = 7^{6}

**zero exponent law**

- anything with a zero exponent is equal to 1

*example: 10 ^{0} = 1*

that's it for now people.. i need 2 study .. hehehehehe..

hopefully someone will actually read dis...

not sure if i explained it right :S..

hehehehehe .. oh well...

u better study anne ..... :P

juzz lve a comment if u guys dont get it ok ...
