Answer:
see below
Step-by-step explanation:
A = pi r^2
If they have the same radius they have the same area
A two circles = pi r^2 +pi r^2
= 2 pi r^2
If we double the radius
A = pi (2r)^2
= pi 4r^2
The combined area of two circles is 1/2 the area as the area of a circle with twice the radius.
Answer:
![\sqrt[7]{b^{15}}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bb%5E%7B15%7D%7D)
Step-by-step explanation:
=> ![b^2*\sqrt[7]{b}](https://tex.z-dn.net/?f=b%5E2%2A%5Csqrt%5B7%5D%7Bb%7D)
=> 
Where bases are same, powers are to be added.
