(10а²у)²*(3ау²)³ =100а⁴у² *27а³у⁶=2700а⁷у⁸
((-1/2)ху³)³*(4у⁵)²= (-1/8)х³у⁶ *16у¹⁰= - 2х³у¹⁶
-(3х⁶у²)³ *(-х²у)⁴= -27х¹⁸у⁶ *х⁸у⁴ = - 27х²⁶у¹⁰
(-5ab⁶)⁴*(0,2a⁶b)⁴= (-5ab⁶*0,2a⁶b)⁴= (-1a⁷b⁷)⁴ = (ab)²⁸
49a⁶b⁴= (7a³b²)²
-25a²b⁴, нельзя так как -25<0<br>
-0.1a⁴b² *(-10a²b⁴)=a⁶b⁶ =(ab)⁶=((ab)³)²
-(-2a⁴)³ *2b⁸=-(-8a¹²) *2b⁸ =8a¹²*2b⁸=16a¹²b⁸=4²a¹²b⁸=(4a⁶b⁴)²
