OpenStudy (notamathgenius):

Yes?

OpenStudy (notamathgenius):

P E M D A S

OpenStudy (jazzyfa30):

ok but i dont know how to do the exponents

OpenStudy (notamathgenius):

b^2 = B^2

OpenStudy (notamathgenius):

A^0=0

OpenStudy (jazzyfa30):

but they want me to multiply

OpenStudy (notamathgenius):

Yes do that on the inside of the () and then multiply the out come

OpenStudy (jazzyfa30):

but what about the one outside

OpenStudy (luigi0210):

actually A^0=1

OpenStudy (jazzyfa30):

but how do i work it out im confused

OpenStudy (luigi0210):

\[(A^2)^3=A^{2*3}\]

OpenStudy (jazzyfa30):

so its a^6

OpenStudy (luigi0210):

In that example yes

OpenStudy (jazzyfa30):

ok so the first part is 6A^2b^4

OpenStudy (luigi0210):

That's simplified already

OpenStudy (jazzyfa30):

???????

@ganeshie8

ganeshie8 (ganeshie8):

\(\large (3a^0b^2)(2a^{-3}b^2)^2\)

ganeshie8 (ganeshie8):

Is this the expression you have been working on ?

OpenStudy (jazzyfa30):

yees

ganeshie8 (ganeshie8):

ok, lets attack the second parenthesis first

ganeshie8 (ganeshie8):

\(\large (3a^0b^2)(2a^{-3}b^2)^2\) ^

ganeshie8 (ganeshie8):

square each term in that parenthesis

ganeshie8 (ganeshie8):

\(\large (3a^0b^2)(4a^{-6}b^4)\)

ganeshie8 (ganeshie8):

fine so far ?

OpenStudy (jazzyfa30):

shouldnt it be -4

OpenStudy (jazzyfa30):

nvm i see

ganeshie8 (ganeshie8):

:) good

ganeshie8 (ganeshie8):

next look at first parenthesis, the easy one -

ganeshie8 (ganeshie8):

we knw that anything to the power 0 = 1. so

ganeshie8 (ganeshie8):

\(\large (3b^2)(4a^{-6}b^4)\)

OpenStudy (jazzyfa30):

what happen to the a variable

ganeshie8 (ganeshie8):

it has a 0 above it, so \(a^0 = 1\)

ganeshie8 (ganeshie8):

if u have 0 in power, that variable just vanishes to 1

OpenStudy (jazzyfa30):

oo ok

ganeshie8 (ganeshie8):

somethingsomethingsomethin^0 = 1

ganeshie8 (ganeshie8):

next - \(\large (3b^2)(4a^{-6}b^4)\) multiply through

ganeshie8 (ganeshie8):

\(\large (3b^2)(4a^{-6}b^4)\) \(\large (12b^6a^{-6})\)

ganeshie8 (ganeshie8):

see if that makes sense

OpenStudy (jazzyfa30):

yes

ganeshie8 (ganeshie8):

great ! its easy if u figure out by urself :)

ganeshie8 (ganeshie8):

next, the last step

ganeshie8 (ganeshie8):

we use this :- \(\large x^{-m} = \frac{1}{x^m}\)

ganeshie8 (ganeshie8):

\(\large (12b^6a^{-6})\) \(\large \frac{12b^6}{a^{6}}\)

OpenStudy (jazzyfa30):

oooo ok

ganeshie8 (ganeshie8):
