14^15/14^5=14^(15-5)=14^10
Hope this kinda helps !!
First you want to collect the like terms, 2a=45 , then divide both sides of the equation by 2 which is a=2/5 , or a=0.4
Answer:
Weight of the solution = 250 grams
Step-by-step explanation:
1) Consider the weight of solution as x grams.
32 % solution = 80 grams salt
32% of x = 80
(32/100)*x = 80
Solving for x:
x = (80*100) / 32
x = 250 grams
Answer:

If you want it written in exponential form it would look like this:

Answer:
r = 6 m
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
Substitute in what we know
37.68 = 2 * 3.14 * r
37.68 = 6.28 r
Divide each side by 6.28
37.68/6.28 = 6.28 r/6.28
6 = r
