Use the formula a^(x/n) = (n)√a^x (note it is a small n)
(5x^4y^3)^(2/9) = Small 9
Convert.
is your answer

So here are a few things about exponents you should know:
- Fractional exponents to radicals:
![x^\frac{m}{n}=\sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%5Cfrac%7Bm%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
- Powering a power:

So firstly, convert the fractional exponent to a radical:
![(5x^4y^3)^\frac{2}{9}=\sqrt[9]{(5x^4y^3)^2}](https://tex.z-dn.net/?f=%285x%5E4y%5E3%29%5E%5Cfrac%7B2%7D%7B9%7D%3D%5Csqrt%5B9%5D%7B%285x%5E4y%5E3%29%5E2%7D)
Next, solve the outer power:
![\sqrt[9]{(5x^4y^3)^2} =\sqrt[9]{5^2x^{4*2}y^{3*2}} =\sqrt[9]{25x^8y^6}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B%285x%5E4y%5E3%29%5E2%7D%20%3D%5Csqrt%5B9%5D%7B5%5E2x%5E%7B4%2A2%7Dy%5E%7B3%2A2%7D%7D%20%3D%5Csqrt%5B9%5D%7B25x%5E8y%5E6%7D)
Your final answer is ![\sqrt[9]{25x^8y^6}](https://tex.z-dn.net/?f=%5Csqrt%5B9%5D%7B25x%5E8y%5E6%7D)

Answer:
1/2 more chocalte or 50% more or 100g more
300g is the new weight
Step-by-step explanation:
200/2=100(50%)
100+200=300g
Volume is length times width times height so you would take 10656/(24*18.5)=24 inches

small=12*8*4=384
large=20*15*9=2700
space=large-small
space=2700-384
space=2316
