2 indices and surds Flashcards
1
Q
a^m x a^n
A
a^m+n
2
Q
a^m / a^n
A
a^m-n
3
Q
(a^m)^n
A
a^mn
4
Q
(ab)^n
A
a^n b^n
(if same indexes you can times base numbers together)
5
Q
a^1/b
A
b roota
6
Q
a^-b
A
1/a^b
7
Q
root a x root b
A
root (ab)
8
Q
rationalising
A
use DOTS
if two surds eg 3+ root 2 + root3 rationalise one then the other eg root 2 then root 3
9
Q
a^nb^n
A
(ab)^n
