Answer:
1563.2
Step-by-step explanation:
If you just multiply 0.3 by 10 you will get 3
Now all you need to do is write 3 or have a number which has unit place value of 3
It is 0.7p= p-250. 0.7p represents the tv with a 30% discount and p-250 represents the tv with a $250 discount.
A. = logb (3/7)^1/2
= logb 3^1/2 - logb 7^1/2
= 1/2(logb 3 - logb 7)
b. = log 7x^3 + log y^5
= log 7 + log x^3 + log y^5
= log 7 + 3 log x + 5 log y
