X=a^n

a is a positive integer less than 10
n is a positive integer less than 10

for example, when a =7 and n=3, x= 7^3 = 343
give 2 of the values of a for which x always ends in the digit a

Describe all the numbers that when rounded to the nearest thousand are 645,000

What values of c and d make the equation true?

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126
