Ответ:

40a^7b^9

Объяснение:

5a²b² - длина

2a³b³ - ширина

4a²b⁴ - высота

V - Объём прямоугольного параллелепипеда равен произведению длины, ширины и высоты параллелепипеда.

V=5a^2b^2*2a^3b^2*4a^2b^4=40a^{2+3+2}b^{2+3+4}=40a^7b^9

(полученное выражение является одночленом стандартного вида -"стандартный вид одночлена – это такой его вид, в котором он представляет собой произведение числового множителя и натуральных степеней разных букв")

a=5a^{2} b^{2} \\\\b=2a^{3}b^{3}\\\\c=4a^{2} b^{4} \\\\\\V=a\cdot b\cdot c=5a^{2} b^{2} \cdot 2a^{3} b^{3} \cdot 4a^{2} b^{4}=40a^{2+3+2} b^{2+3+4} =\boxed{4\cdot 10a^{7} b^{9}}
