Question

помогите, пожалуйста. ​

Answer 1

Ответ:

а)45ху•14хz³•27y³/7z²•81y²•5xz=18xy²

б)74a³b•b³•3ac³/c4•111a5=2b4/ac

((x²-10x+25)/(x²-25))³:((x-5)/(x+5))³=1

((x-5)²/(x-5)(x+5))³:((x-5)/(x+5))³=1

((x-5)/(x+5))³:((x-5)/(x+5))³=1

5)(x/y²)²=x²/y^4; б)(-2а³/с^5)³=-8а^9/с^15

в)(с²/b)³•(b²/c^5)²=c^6•b^4/b³•c^10=b/c^4
