The value of this expression is 16. In exponential problems you can multiply the base by the number of times the exponent is. In this case it would be: 2*2*2*2. Then just multiply and get the product of 16.
The question is a little confusing, but a fraction that is equal to 2 using 3 as a denominator is 6/3. Any addition to the numerator will make the number larger than 2; so 7/3, 10/3, 20/3 are all greater than 2.
Answer:
43.35
Step-by-step explanation:
Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
