Step 1, Jenny should've multiplied 4 times 5 instead of writing 5 as the exponent.
Step 2, Jenny should've calculated the value of 45
to be 1,024.
Step 2, Jenny should've calculated the value of 4 to the 5th power to be 1,024.

Jenny made a mistake in Step 1. Instead of writing \( 45 \) (which suggests she is raising 4 to the power of 5), she should have multiplied \( 4 \cdot 5 \).
So the correct answer is: Step 1, Jenny should've multiplied 4 times 5 instead of writing 5 as the exponent.
