Answer:
Option B is correct.
![5\sqrt[3]{10} + 4\sqrt[3]{10}](https://tex.z-dn.net/?f=5%5Csqrt%5B3%5D%7B10%7D%20%2B%204%5Csqrt%5B3%5D%7B10%7D)
Step-by-step explanation:
Given the equation: ![9\sqrt[3]{10}](https://tex.z-dn.net/?f=9%5Csqrt%5B3%5D%7B10%7D)
We can write 9 as:
9 = 5+ 4
then;
![(5+4)\sqrt[3]{10}](https://tex.z-dn.net/?f=%285%2B4%29%5Csqrt%5B3%5D%7B10%7D)
Using distributive property:

Apply distributive property:
![5\sqrt[3]{10} + 4\sqrt[3]{10}](https://tex.z-dn.net/?f=5%5Csqrt%5B3%5D%7B10%7D%20%2B%204%5Csqrt%5B3%5D%7B10%7D)
Therefore, the expression which is equivalent to
is ![5\sqrt[3]{10} + 4\sqrt[3]{10}](https://tex.z-dn.net/?f=5%5Csqrt%5B3%5D%7B10%7D%20%2B%204%5Csqrt%5B3%5D%7B10%7D)
Remember these two combinations: logab=loga+logb, log(a/b)=loga-logb
3logx=logx^3
(1/2)log(x+2)=log(x+2)^(1/2)
2log(z-4)=log(z-4)^2
so the given expression can be combined into log{[(x^3)(z-4)^2]/(x+2)^(1/2)}
Answer:
3 years
Step-by-step explanation:
let the number of years required be x
hence
42+x+44+x = 4(7+x+5+x+2+x)
86+2x = 4(14+3x)
86+2x = 56+12x
2x-12x = 56-86
-10x = -30
x = 3
The pack of pencils weighs 21.6 grams because 0.9 times 24 is 21.6
Combine: -4 (33y+2)/ 23
simplify: -132y/23 -8/23
:D hope i helped
