Rewrite using a single positive exponent
8^-3 × 8^-6

Step-by-step explanation:

8^-3 can be written 1/8^3

same way, 8^-6=1/8^6

the multiplication:

(1/8^3)(1/8^6)=1/8^9

remember when you multiply the power you add the exponents

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.
