Answer:
![x^2\sqrt[3]{x}](https://tex.z-dn.net/?f=x%5E2%5Csqrt%5B3%5D%7Bx%7D)
Step-by-step explanation:
The relevant properties of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
1/a^b = a^-b
__
Your expression simplifies to ...
![\displaystyle x^{\frac{6}{3}+\frac{6}{9}-\frac{1}{3}}=x^{\frac{7}{3}}\\\\=x^2\sqrt[3]{x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5E%7B%5Cfrac%7B6%7D%7B3%7D%2B%5Cfrac%7B6%7D%7B9%7D-%5Cfrac%7B1%7D%7B3%7D%7D%3Dx%5E%7B%5Cfrac%7B7%7D%7B3%7D%7D%5C%5C%5C%5C%3Dx%5E2%5Csqrt%5B3%5D%7Bx%7D)
Answer:
4
Step-by-step explanation:
the ratio from 9 to 18 is times 2 so multiply 2 by 2
Answer:
Multiply/divide both sides by the same non-zero constant
Step-by-step explanation:
5x = 20
Divide each side by 5
5x/5 = 20/5
x = 4

How to calculate the distance between two points</h3>
The formula for calculating the distance between two points is expressed as:
A = √(x2-x1)²+(y2-y1)²
Given the coordinate points X(–12, –6) and Y(5, 6). The distance between them is expressed as;
XY = √(5+12)²+(6+6)²
XY = √(17)²+(12)²
XY = √269 + 144
XY = 20.8
Hence the approximate length of line segment XY is 20.8 units

Answer:
d =13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance across the circle, going through the center
d = 13 cm
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm
