HELP PLEASE I ONLY GOT TODAY I NEED HELP ON 41,42,43, and 44 PLEASE HELP ME I NEED THIS TO GET MY GRADE UP

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.
