Answer:
![24\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=24%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
Step-by-step explanation:
The exponent rule that applies to products like this is ...
... (a^b)(a^c) = a^(b+c)
In your problem, this is
... x^(1/3)·x^2 = x^(1/3 +2) = x^(1/3 +6/3) = x^(7/3)
This fractional exponent translates to the root of a power:
... = (x^7)^(1/3)
In typeset form, it is ...
![\sqrt[3]{x^{7}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B7%7D%7D)
You have already figured correctly that the coefficient is 3·8 = 24.
350x300=105000m squared
1km=1000m
So, 105000=105km squared
Answer: Choices C and D
Explanation:
Positive values of 'a' will make the parabola open upward.
Think "positive" as in "happy smile" to help remember this. In contrast, if 'a' is negative, then it is angry or sad to make a frown.
Answer:
x = 16
Step-by-step explanation:
The sum of the angles of a triangle are 180
128+ 2x-3 +23 = 180
Combine like terms
2x+148=180
Subtract 148 from each side
2x+148 -148 = 180-148
2x = 32
Divide by 2
2x/2 = 32/2
x =16
