(p^(2))/(3)_p=9
Replace the variable p with 9 in the expression.
((9)^(2))/(3)
Expand the exponent (2) to the expression.
(9^(2))/(3)
Squaring a number is the same as multiplying the number by itself (9*9). In this case, 9 squared is 81.
(81)/(3)
Reduce the expression (81)/(3) by removing a factor of 3 from the numerator and denominator.
