Easy peasy
just use PEMDAS and some exonential laws



also another is
![x^{\frac{m}{n}}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
so
![[3(2a)^{\frac{3}{2}}]^{2}](https://tex.z-dn.net/?f=%20%5B3%282a%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%5D%5E%7B2%7D%20)

Convert to improper frist
2 and 7/8=16/8+7/8=23/8
2 and 1/4=8/4+1/4=9/4
(23/8)/(9/4)
make bottom 1
times the whole thing by (4/9)/(4/9)
(92/72)/(36/36)=
92/72=
23/18

Answer:$7.56 because 72 times 0.105 is 7.56
Step-by-step explanation:
I believe the answer is 13 I think but I’m not sure but I just did the math off of the top of my head
