Answer:
Its the last one a^2/b.
Step-by-step explanation:
(a^6 b^-3)^1/3
= a ^(6 * 1/3) b^(-3*1/3)
= a^2b^-1
= a^2/b.
Answer:
whole number and a fraction
Answer:
x=2.65
Step-by-step explanation:
First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

Next, add 5 to both sides:

Then divide both sides by 4:

Answer:
-100
