all work is pictured and shown
Answer:
A= 4.5×10^11
B= 3.5×10^3
Step-by-step explanation:
A
(5×10^3)= 5000
(9×10^7)=90000000
multiply both of them
=450000000000 or 4.5×10^11
B
(7×10^5)=700000
(2×10^2)=200
700000÷200
3500 or 3.5×10^3
Work shown above! Answer is y = -6(1/3)^x
edit: at the bottom it says "be must be 1/3" I meant "b must be"
