Answer:
Step-by-step explanation:
41. -3
42. 3
43 y^19
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.
9.95 + 2.99z
M x M / x + y =4
128
