The expression is:


(3^2)^3

When you raise an exponent to another exponent, such as this case, you need to follow this rule:


(x^m)^n=x^(m\cdot n)

The rule is to multiply the two exponents.

Using that rule with the expression we have:


(3^2)^3=3^(2\cdot3)

Since 2*3=6:


(3^2)^3=3^(2\cdot3)=3^6

The simplified expression is:


3^6

If what you need is the numerical value of the expression, the next step will be to multiply 3 by itself the number of times the exponent indicates, in this case, multiply 3 six times by itself:


3^6=3*3*3*3*3*3

Solving the multiplications:


3^6=729

Answer:


(3^2)^3=3^6=729
