3 * [(7 - 4)^4 / 9]
First, let's work within the parentheses:
7 - 4 = 3
Now, substitute that value back into the expression:
3 * (3^4 / 9)
Calculate 3 raised to the power of 4:
3^4 = 81
Now divide 81 by 9:
81 / 9 = 9
Finally, multiply the result by 3:
3 * 9 = 27
So, the value of the expression is 27.
