Step-by-step explanation:

41. -3

42. 3

43 y^19

Answer:

41 )  b²/b^8=b^-6 ( when divide subtract exponents)

42 ) x.x².x^6=x^9   ( when multiply add exponents)

43) y^25/y^19 = y^6

44 )  when you divide numbers you make it smaller, so subtract the exponent will make the value of the base smaller.
