360/30 you divide it by each other and the answer is 12
Answer:
![\sqrt[8]x = x^\frac{1}{6}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7B6%7D)
Step-by-step explanation:
Given:
![\sqrt[6] x](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%20x)
Required
Represent as an exponent
In indices, we have:
![\sqrt[n]x = x^\frac{1}{n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5Dx%20%3D%20x%5E%5Cfrac%7B1%7D%7Bn%7D)
By comparison:
![\sqrt[8]x = \sqrt[n]x](https://tex.z-dn.net/?f=%5Csqrt%5B8%5Dx%20%3D%20%5Csqrt%5Bn%5Dx)
Apply this law to the given expression:
We have:
Answer: yes because the x could be 4 then 7 times 4 is 28 which would make this math sentence true
Step-by-step explanation:
Answer:
x = 8
y = 3
Step-by-step explanation:
Area = 1/2 √6 (6√2 + √8) Remove the brackets
Area = 1/2 ( 6*√12+ √48)
Area = 1/2 (6*√12 + 4√3) Multiply by 1/2
Area = 3√12 + 2√3
Area = 3*2√3 + 2√3
Area = 6√3 + 2√3
Area = 8√3
Answer:
(5, 11 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 4 → (1)
y = 2x + 1 → (2)
Substitute y = 3x - 4 into (2)
3x - 4 = 2x + 1 ( subtract 2x from both sides )
x - 4 = 1 ( add 4 to both sides )
x = 5
Substitute x = 5 into either of the 2 equationsfor corresponding value of y
Substituting into (2)
y = 2(5) + 1 = 10 + 1 = 11
solution is (5, 11 )
