[Dyldodeath]

in the non-calc section

how do u work out - (3x104)x(2x10-6)

lol im good at asking questions on here

*the 4 and -6 are indices (to the power of)




THANKS for help

You add the indices, then multiply the other numbers. It should get you the answer.. (I think)

 

[keenith]

3x10^4 X 2x10^-6

6x10^4+(-6)

6x10^-2

hope this helped

 

[Dyldodeath]

ah thought so

but shoud the it be minus coz + -

btw thx

 

[keenith]

np

no.

it's not minus because 10^-6 means 0.000001 not -0.000001

And 10^4 = 10000

so 3 x 10^4 x 2 x 10^-6 = 6 x 10^-2 = 0.06

 

[Dyldodeath]

sweet as...
thx for quick response lol

 

[keenith]

no.

ehh he was refering to the indice

?

Even though he was referring to indices, it's not minus. It's plus.

uhh if you look at my working out its a minus and will be a minus

Yes. But you got his comment wrong.

He thought it was minus because plus times minus is minus where that rule doesn't apply here.

And by "plus" I am referring to the whole number not the indices.

he never referred to the whole number though

and he never said minus a minus is a plus as well

This quote will clear that up.

And apparently my comment after this quote cleared his doubt. What does that mean?

I wouldn't argue with Iyounou when it comes to mathematics dude.
And plus, you're in year 10 so you aren't as competent as the people who are doing their HSC. Sorry dude, its the way it goes.

Doesn't mean you're correct.
Double read what is written before you argue dude.
