(21²+10²)½ = 23.25= 23.3
Answer:
x = 4
which agrees with the third listed answer among the given options
Step-by-step explanation:
We can re-write the logarithmic equation using the properties of logarithms:

Therefore, the arguments of the log functions must also be equal (and we can solve for "x" by noticing that this expression is the perfect square of a binomial:

and for this equation to verify, x must be 4
Answer:
Put 4 in the place of x then you'll get

I feel like it might be the second one
