Question

how do i solve this??
0.0004=(4000000)/(d^(2))
please help >.<

Answer 1

Isolate 'd'

Answer 2

Would it be easier if you made a substitution in the beginning, \(m =d^2\) and then wrote out your equation like this: \[0.0004=\frac{4000000}{m}\] then solve for 'm'.

Answer 3

Once you are done you just need to substitute back and solve for 'd'.
