    Find the difference in voltage at different points in a circuit.

    Thanks! For the second part, following your advice, I did: Vc1 = IR = (1.00 A) (2 Ω) = 2 V Vc1 + Vc2 = 50V 2 V + Vc2 = 50 V Vc2 = 48 V

    How to prove (a^c)^d = a^(cd) without knowing the values of c and d?

    Thank you tiny-tim, the advice helped me finish the proof. Sorry I didn't respond until now, had other work as well.

    How to prove (a^c)^d = a^(cd) without knowing the values of c and d?

    Homework Statement The problem is in the title: Prove (a^c)^d) = a^(cd) Homework Equations N is the set of natural numbers. (ab)^n = (a^n)(b^n) a^(p+n) = (a^p)*(a^n) ((a^p)(a^n)) * a = (a^p)(a^(n+1)) The Attempt at a Solution c = p-q; d = j-k; p,q,j,kεN (by definition...
