Answer:
Cara multiplied only 4 and 7 together and did not multiply 4 and 13.
Step-by-step explanation:
Let us evaluate the given expression step by step,
We can evaluate this expression in two ways; either by subtracting -13 from 7 and then multiply by 4 or by multiplying 4 to 7 and -13.
Now let us see where Cara made an error. We can see Cara just multiplied only 4 and 7 together and did not multiply 4 to 13.
Therefore, Cara made error in her first step.

Answer:
Step-by-step explanation:
Data provided:
ln(x) + 2 ln(y) − 3 ln(z)
Now,
From the properties of log function,
ln(A) + ln(B) = ln(AB)
n × ln(x) = ln(xⁿ)
and,
ln(A) - ln(B) =
applying the properties in the given equation
we get
⇒ ln(x) + 2 ln(y) − 3 ln(z)
or
⇒ ln(x) + ln(y²) - ln(z³) (using n × ln(x) = ln(xⁿ))
or
⇒ ln(xy²) - ln(z³) (using ln(A) + ln(B) = ln(AB) )
or
⇒ (using ln(A) - ln(B) =
