Llana [10]
You add all the percentages up and it will give you 64. take 64 and put it over 100 because percentages as a fraction will always be the amount over a 100.  
so its 64/100 multiply by 4000/1. 64*4000= 256000 over 100. 256000 divided by 100 = 2560

$2560

What is the answer to this question please explain (picture included)
Yakvenalex [24]
Easy peasy
just use PEMDAS and some exonential laws

(x^{m})(x^{n})=x^{m+n}
(x^{m})^{n}=x^{mn}
(ab)^{m}=(a^{m})(b^{m})

also another is x^{\frac{m}{n}}=\sqrt[n]{x^{m}}

so

[3(2a)^{\frac{3}{2}}]^{2}=
(3^{2})((2a)^{\frac{3}{2}}^{2})=
(9)((2a)^{\frac{3}{2}}^{2})=
(9)((2a)^{\frac{6}{2})=
(9)((2a)^{3}) =
(9)(8a^{3}) =
72a^{3}
