Question

помогите решить пожалуйста​

Answer 1

2) (5²*6⁴*12²)/(15²*9³)=(5²*2⁴*3⁴*3²*2⁴)/(3²*5²*3⁶)=(5²*2⁸*3⁶)/(3⁸*5²)=2⁸/3²=256/9= 28 4/9

3)(12²*4³*6²)/(8²*18³)=(3²*4²*4³*2²*3²)/(2²*4²*2³*9³)=(3⁴*4⁵*2²)/(2⁵*2⁴*3⁶)=(2¹⁰*2²)/(2⁹*3²)=2¹²/(2⁹*3²)=2³/9=8/9

4) ( (3³)³*9⁷*2²)/(81⁵*2³)=(3⁹*3¹⁴*2²)/(3²⁰*2³)=(3²³*2²)/(3²⁰*2³)=3³/2=27/2
