Answer:The answer for the first one is log2(.25)=-2
The answer for the second one is 8^3=512
Step-by-step explanation:
This is the division for your problem hope this helps!
For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
Answer:
a. 5
b. 545
c. 0
Step-by-step explanation:
These are straightforward division problems, easily solved using your own memorized multiplication facts, or using a calculator.
a. 20 ÷ 4 = 5 means 5 × 4 = 20
b. 2725 ÷ 5 = 545 means 545 × 5 = 2725
c. 0 ÷ 5 = 0 means 0 × 5 = 0
