Question

Make 'n' the subject of the formula:
s=(2a/3)sq.rt (b2-n2), where 0 13 years ago

Answer 1

i don't really understand the point

Answer 2

u want just solve the eqn

Answer 3

just a correction its (b sq. - n sq.) and yes I just want to solve the equation. Thnx in advance :)

Answer 4

i think something wrong with the queastion

Answer 5

\[s=\frac{ 2a }{ 3 }\sqrt{b ^{2}-n ^{2}} \]

Answer 6

s^2= (4a/9)b^2 -n^2
(9/4a)a^2=b^2 -n^2
s^2=(9/4a^3)-n^2=b^2

Answer 7

so u now just take the cubic eqn

Answer 8

I still can't figure it out :(

Answer 9

sorry i would help u if i know
