Question

Найдите значенние выражения.

Answer 1

(1/15)^3 = (3*5)^-3
(1/75)^-4 = (3^4)(5^8)
9/125 = (3^2)(5^-3) = 3^2(5^-3)
0,2^-2= (1/5)^-2 = 5^2

((3*5)^(−3)*((3^4)*(5^8))*(3^2)*(5^−3)+5^2)/17,5 =

=(3^(−3)*(3^4)*(3^2)*(5^(−3))*(5^8)*(5^−3)+5^2)/17,5 =

= ((3^3)*(5^2)+5^2)/17,5 = (5^2)(27+1)/17,5 = 25*28/17,5 = 700/17,5 = 40
