Which number is greatest? 2.89 times 10 Superscript negative 8 1.997 times 10 Superscript 2 8.9 times 10 Superscript negative 6 5 times 10 Superscript negative 6

Solution:

Given that the numbers are:

We have to find the number that is greatest

Convert the numbers to decimal

We can clearly see that, 199.7 is greatest number

Thus the greatest number is

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
