    2^n = 5 e 2^p = 9

    2^(n-p+1)

    2^n-2^p+2^1
    5 — 9 + 2
    — 2

  • Rais quadrada de 2p

    propriedades e exemplos:

    2^x.2^2=2^{x+2}

    2^{x+3}=2^x.2^3

    outra propriedade:

    2^{-1}= frac{1}{2}

    para muda o sinal do expoente basta inverte o numero.

     (frac{5}{2})^{-2} = (frac{2}{5} )^2
