a=9

step-by-step explanation: lmk if you need a explanation

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:

26 + 8 = 2*13 + 2*4 = 2*(13+4) = 2*(17)

a magnifying glass is a convex lens which produces a magnified image of an object. for a magnified image to be observed the distance between the object and the lens has to be shorter than the focal length of the lens.
