1. can someone solve 2000 = 4𝐾^0.75 * L^0.25 where k=3/10 L. i tryed to solve this by adding the powers 2000=4(3/10 L^1) however i get an answer of 5000/3 which is not the correct answer the correct answer is 5000(10/3)^.75

2. We are given to solve for $L$:

$\displaystyle 2000=4K^{\frac{3}{4}}L^{\frac{1}{4}}$

Divide through by 4:

$\displaystyle 500=K^{\frac{3}{4}}L^{\frac{1}{4}}$

We are told:

$\displaystyle K=\frac{3}{10}L$:

$\displaystyle 500=\left(\frac{3}{10}L\right)^{\frac{3}{4}}L^{\frac{1}{4}}=\left(\frac{3}{10}\right)^{\frac{3}{4}}L$

Hence:

$\displaystyle L=500\left(\frac{10}{3}\right)^{\frac{3}{4}}$
