4n, 6b, and -8 are the terms
To find the distance<span> between two points (x</span>1,y1) and (x2,y2<span>), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below.</span>
It looks like they're multiplied, then you can simply add the exponents,
b⁸ * b⁴ = b⁸⁺⁴ = b¹²
remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b
so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²
Remember that ratios are essentially fractions without fraction bars...
If they asked to find the ration of 19.50 to 16.25 you would set them up like so....
19.50 : 16.25 -----> since fractions can be simplified so can ratios in the same manner
the ratio you would end up with is <u>6 : 5</u><u />
Ratios can be easily remembered and solved if you understand the link between them and fractions.
I hope this helps! :D
