To solve this expression, we follow the order of operations which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
First, let's evaluate the expressions within the parentheses:
7⁵ = 7 7 7 7 7 = 16807
Now, let's square the result:
(16807)² = 16807 * 16807 = 282475249
Finally, let's divide the result by 7³:
282475249 / 7³ = 282475249 / (7 7 7) = 282475249 / 343 = 823543
Therefore, the final answer is 823543.
