What is the cube root of 216x^9y^18?
PilotLPTM [1.2K]

Answer:

The cube root of given expression is 6x^3y^6.

Step-by-step explanation:

The given expression is

\sqrt[3]{216x^9y^{18}}

It can be written as

Use the exponent property: a^{mn}=(a^m)^n

\sqrt[3]{216x^9y^{18}}=\sqrt[3]{6^3(x^3)^3(y^6)^{3}}

\sqrt[3]{216x^9y^{18}}=\sqrt[3]{(6x^3y^6)^{3}}

\sqrt[3]{216x^9y^{18}}=6x^3y^6

Therefore the cube root of given expression is 6x^3y^6.

Complete the equation of the line through [1,4] and [2,2]
son4ous [18]

First find the slope of the line so change in y over change in x so 4-2/1-2 which is 2/-1 so -2 is your slope then plug that as well as a point from above to find your y intercept so y=mx+b 2=-2(2)+ b then you have 2=-4+b then add 4 to each side and you find b is six then you make ur equation from your slope and y int(b) y=-2x+6

Solve for x. Show your work with proper statements and notation.
9966 [12]

Answer:

x = 26

Step-by-step explanation:

The sum of the angles around point O = 360°, thus

x + 3x + 256 = 360 , that is

4x + 256 = 360 ( subtract 256 from both sides )

4x = 104 ( divide both sides by 4 )

x = 26
