-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

(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
