Remember, the numerator of an exponenent represents the root. As well, a negative exponent means to take the reciprocal of the positive exponent (
.
So, 
is equal to ![\sqrt[3]{64^{-1}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%5E%7B-1%7D%7D)
which is 1/4, because 1/4*1/4*1/4 is 1/64 (1/64 cubed root is 1/4).
For example, ![a^{b/c} = \sqrt[c]{b^{b}}](https://tex.z-dn.net/?f=a%5E%7Bb%2Fc%7D%20%3D%20%5Csqrt%5Bc%5D%7Bb%5E%7Bb%7D%7D)
The answer is c.
Answer: 24*70=1680
Step-by-step explanation:
Answer Perimeter = 33in
Step-by-step explanation:
AC = 20
BD = 20
AB = 13
O is the midpoint
OD = OC = 20/2 = 10
AB = DC = 13 in
P = DC + OD + OC = 13+10+10 = 33in
Answer:
(4,0) and (2,0)
Step-by-step explanation:
For an x-intercept, y=0, so now we have:
(x-4)(x-2)=0
Anything multiplied by 0 is 0, so (x-4)=0 and/or (x-2)=0
(x-4)=0
x=4
(x-2)=0
x=2
The x-intercept co-ordinates are: (4,0), (2,0)
