1st character = 26 possibilities ( 26 letters in the alphabet)
2nd character = 26 possibilities
3rd character = 26 possibilities
4th character = 10 ( 10 special characters)
26 x 26 x 26 x 10 = 175,760 combinations
PEMDAS tells us to use multiplication and division before addition and subtraction.
<u>-5(8) </u>÷ 10 - <u>14 ÷ 7</u> - <u>(-2)(3)</u>
<u> -40 ÷ 10</u> - 2 - -6
<u>-4 - 2 </u> + 6 <em>two negatives make a positive so - - 6 = + 6</em>
<u> -6 +6</u>

<span>Drake can meet his $750 planned savings goal with either concept. After 4 weeks, he was $30 less than where he planned to be ($450 instead of $480). If he simply added $250 after two more weeks, he would be at $720 instead of $750, and would have to wait one more week to take the class. Conversely, if he added $15 to the next two weeks' savings, he would recoup the $30 he pulled out of the savings in those two weeks and would be back on the path to being able to take the course at the end of the 6-week period as originally planned.</span>
Answer: 9^-8
Step-by-step explanation:
To get single positive exponent,

9^-5-3
So
9^-8
