Хелп , еще 3) 3^15 умножить на 4^13/144^7​

1) 3;

2) 3/16;

3) 3/4.

Пошаговое объяснение:

1) (3^10•27^3)/9^9 = (3^10•(3^3)^3)/(3^2)^9 = (3^10•3^9)/3^18 = 3^19/3^18 = 3.

2) (5 1/3)^7•(3/16)^8 = (16/3)^7•(3/16)^7•3/16 = (16/3•3/16)^7•3/16 = 1^7 • 3/16 = 1 • 3/16 = 3/16.

3) (3^15•4^13)/144^7​ = (3^13•3^2•4^13)/(12^2)^7 = 3^2•(3^13•4^13)/(12)^14 = 3^2•(12^13)/(12)^14 = 9/12 = 3/4.
