Choose 1

(Choice A)
A
Replace one equation with itself where a quantity is added to only one side

(Choice B)
B
Replace one equation with itself where the same quantity is added to both sides

(Choice C)
C
Replace only the right-hand side of one equation with the sum/difference of the right-hand sides of both equations

(Choice D)
D
Replace one equation with the sum/difference of both equations

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

step-by-step explanation:

im not sure what the answer is

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
