Product of (x + 5)(x + 2)

x^2+7x+10

Step-by-step explanation:

x×x=x^2

5×x=5x

2×x=2x

5x+2x=7x

5×2=10

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:
