this time divide
Parth (parthkohli):
Yep! What is 5.2/1.3??
OpenStudy (lgbasallote):
what's 5.2/1.3?
Parth (parthkohli):
Remember that 5.2/1.3 is 52/13
Parth (parthkohli):
and then find 10^12/10^-5

OpenStudy (lgbasallote):
(5.2/1.3) x (10^12 / 10^-5) <--remember this
Parth (parthkohli):
And then just write the multiplication of 5.2/1.3 and 10^12/10^-5
OpenStudy (lgbasallote):
@alynamarie wanna reply any time? lol
Parth (parthkohli):
Also remember that \(10^{12} \div 10^{-5}= 10^{12 - (-5)} \) :)

good
Parth (parthkohli):
Yes!
OpenStudy (lgbasallote):
sp what's 10^12 / 1)^-5?
Parth (parthkohli):
sp?
OpenStudy (lgbasallote):
remember 10^x / 10^y = 10^(x-y)

therefore 10612 / 10^-5 = 10^(12 - (-5))
OpenStudy (anonymous):
10^17
Parth (parthkohli):
@alynamarie Need any help? :)
OpenStudy (lgbasallote):
that's 10^12 not 10612
Parth (parthkohli):

Parth (parthkohli):
@Master.RohanChakraborty Can you explain what is wrong with my explanation so I could rectify?

Parth (parthkohli):
*DANCES*
Parth (parthkohli):
@alynamarie Keep it up! :)
OpenStudy (anonymous):
or should it be 4x10^17
instead of 4.0x10^17 ?
Parth (parthkohli):
Both apply :)

4.0 = 4 :D
OpenStudy (lgbasallote):
i prefer the one with decimal...it's more proper :)
Parth (parthkohli):
Both work great! ^_^
OpenStudy (anonymous):
ok
OpenStudy (lgbasallote):
but the one in decimal is the more customary ^_^

Nah not really
OpenStudy (lgbasallote):
you'll see...when you go to college
OpenStudy (lgbasallote):
in physics and chemistry..they use decimal
Parth (parthkohli):
It is, but you really don't have to argue about it.
OpenStudy (lgbasallote):
i was saying that i preferred it ^_^
