I don't understand how I am supposed to solve if i have something like (-7) to the power of -2... or 3/4 to the power of -1

  • math -

    -7^ (-2), put it divided by 1.
    -1/(7^2) when you place the exponent to the denominator, change the sign, same goes if you have a negative exponent on the denominator, bring it to the numerator and change the sign.
    -1/49

  • math -

    (3/4)^(-1). Just switch the fraction to
    4/3 , because its the whole fraction raised to -1.

    if ( 3^(-1) ) / 4 ==> 1/(3*4)=1/12
