To solve this problem you must apply the proccedure shown below:
1. You have the following logarithm:
<span>log(2)n=4
2. Therefore, you con rewrite it as below:
loga(b)=logb/loa
</span>
3. Therefore, you have:
log(2)n=4⇒log(n)/log(2)=4
4. Then, you obtain:
log(n)=4log(2)
5. Therefore, as you can see, the answer for the exercise shown above is the last option, which is:
log(n)=4log(2)
Answer:
42
Step-by-step explanation:
Since the scale factor is 2:7, you can divide the given number by 2 then multiply it by 7, so 12/2x7=42
(100^5) * 4000 = 10000000000 * 4000 = <span>4 * 10^13</span>
Answer:
x = -7
Step-by-step explanation:
−30=5(x+1)
Divide each side by 5
-30/5=5/5(x+1)
-6 =x+1
Subtract 1 from each side
-6-1 = x+1-1
-7 =x
