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

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

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

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

:) 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
