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.
To calculate the GCF, you need to list all the prime numbers that will go into each number listed
12: 2, 2, 3
60: 2, 2, 3 5
68: 2,2,17
Now you circle the numbers that are the same in each.
GCF: 2, 2
Multiply these numbers to find the GCF: 4
Answer:
.36666667
Step-by-step explanation:
To solve for x we proceed as follows:
from the laws of logarithm, given that:
log_a b=c
then
a^c=b
applying the rationale to our question we shall have:
log_5 x=4
hence
5^4=x
x=625
Answer: x=625
