(-)exponents mean reciprocals so x^-1=1/x so 2^-2=1/2^2=1/4 3^-3=1/3^3 =1/9
To calculate 3 − 3 2 − 2 , you convert the negative exponents to their reciprocal forms, resulting in 4 27 or 6.75. This uses the property that x − n = x n 1 to simplify the expression. Finally, the division of fractions leads to the final answer 6.75.
