Answer:

12^9

Step-by-step explanation:

12^8 * 12^-8

according to law of integers, since both numbers are the same we can work with their roots, and the multiplication would be addition;

8+(-8)= 0

(12*12)^0 ----numerator

(denominator)

12^-9

division = subtraction in the laws of integers

0-(-9)= 0+9=9

(12*12)/12= 12

=12^9

KATRIN_1 [288]

Answer:

It would take Al 7.5 days to build the grill alone.

Step-by-step explanation:

Since Tim and Al are bricklayers, and Tim can construct an outdoor grill in 5 days, and if Al helps Tim, they can build it in only 3 days, to determine how long would it take Al to build the grill alone should be done the following calculation:

1/5 + X = 1/3

0.20 + X = 0.333

X = 0.333 - 0.20

X = 0.1333333

X = 1 / 7.5

Therefore it would take Al 7.5 days to build the grill alone.
