P%5BCR%5D=%28n%2Api%5E2%2AE%2AA%29%2F%28%28L%2Fsqrt%28I%2FA%29%29%5E2%29 Start with the given equation.


P%5BCR%5D=%28n%2Api%5E2%2AE%2AA%29%2F%28L%5E2%2F%28sqrt%28I%2FA%29%29%5E2%29 Square each term


P%5BCR%5D=%28n%2Api%5E2%2AE%2AA%29%2F%28L%5E2%2F%28I%2FA%29%29 Square the square root to eliminate it.


P%5BCR%5D=%28n%2Api%5E2%2AE%2AA%29%2F%28%28A%2AL%5E2%29%2FI%29 Multiply the by the reciprocal


P%5BCR%5D=%28n%2Api%5E2%2AE%2AA%2AI%29%2F%28A%2AL%5E2%29 Multiply the by the reciprocal again


P%5BCR%5D=%28n%2Api%5E2%2AE%2Across%28A%29%2AI%29%2F%28cross%28A%29%2AL%5E2%29 Cancel out like terms.


P%5BCR%5D=%28n%2Api%5E2%2AE%2AI%29%2F%28L%5E2%29 Simplify


From here, you can now solve for I
