Introduction and general help regarding powers..
Hi there, Good evening all.
Ok, Ive just started my HNC in electrical engineering (1 month in via open learning)and to be honest, I'm struggling. I understand all the concepts of the equations regarding bending moments, shear force diagrams etc but i cant seem to get to grip with the equations.. I have a level maths but i achieved this 8-9 years ago so i'm after a bit of directional help.
Q1, what or how is the best way to write to the 'poer minus 4' ( the minus sign up in the air)?
Q2, Can anyone explain to me in simple terms the best way to understand poers e.g. 1mm4=(1x10^3)4=1x10^12M
Also if there is any good reading material out there that may be useful please point me in the right direction. Much appreciated.

Hi Harrison01! Welcome to PF!
"x to the minus 4"
if you want that to the 4th power, that's (10-3 m)4,=10-12 m4
("m4" is like "s2", it's a maths thing, it doesn't mean anything you can draw)

cheers for the reply tim,
But what is the best way to write to the minus 3. is there a common symbol as i cant get the - to go higher than the norm..
