Answer:

The number in standard notation is 90 000.

Step-by-step explanation:

The important idea in this exercise is to know the meaning of each operation, and the order we must follow to operate with them.

Recall that the operation with preference is the exponentiation. So, the fisrt calculation must be 10^4, which means the multiplication of 10 by itself four times:

10^4 = 10 x 10 x 10 x 10 = 10000 (ten thousand).

Then, our number is 9 x 10000 = 90000 (ninety thousand)
