Rewrite the following expression as a number with no exponents. Explain or show your reasoning 7^-3/ 7^5

1/5,764,801

Step-by-step explanation:

We have this as follows

All we have to do is use the laws of indices

We have it that;

a^-x = 1/a^x

a^x/a^y = a^(x-y)

Applying these laws;

7^-3/7^5

= 7^-3-5

= 7^-8

= 1/7^8

= 1/5,764,801

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
