To solve the expression using PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right), we can break it down step by step:

Step 1: Evaluate 9^9
This is the exponentiation step.
9^9 = 387,420,489

Step 2: Multiply 456 and 99
456 * 99 = 45,144

Step 3: Divide the result from Step 2 by 7
45,144 / 7 = 6,449

Step 4: Multiply the result from Step 3 by the result from Step 1
6,449 * 387,420,489 = 2,510,214,473,261

Therefore, 456 * 99 / 7 * 9^9 = 2,510,214,473,261.
