# Powers! (and volumes) watch

1. Basic question I know, but I'm unsure as to how to go about working it out:

Is (20 x 10^-6 m)^3

the same as:

(2 x 10^2)^3 x (10^-6)^3 dm^3

?
Thanks.

Was fortunately browsing.

1m=10dm

Your markings of dm^3 were a touch convoluted so I just decided to play with the numbers.
Thanks! (I just worked it out to be true as well)

Haven't even finished hinting
1m = 10dm

so to see if they're equal, put the top one into dm by making it and expand brackets

Spoiler:
Show
and yes they are equal
