Answer:
bottom right 8 x 10^1
Step-by-step explanation:
multiply the numbers (2x4 is 8)
add the exponents of 10 (-3+4 is 1)
so the answer is the bottom right 8 x 10^1
10/25 = 2/5
Divide by 5 to get simplest form
40 weeks because you divide 500 by 4 which is 125 then you guess and check to make 40 multiplied by 125 is 5,000
