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: (x2)(x3)= x5

quotient law

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

example: x4÷x3= x1

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: (73)2 = 76

zero exponent law

- anything with a zero exponent is equal to 1

example: 100 = 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
