Answer:
ln 4
Step-by-step explanation:
plus(+) will become times and minus(-)will become divide. Combine all together as all are in terms of ln
ln (2x8)/4
=ln 4
Answer: you add them all up
Step-by-step explanation: you can get the answer from above and dont trust this answer.
Yes they are that’s correct
7.
remember
(ab)/(cd)=(a/c)(b/d)
we can split them up
and
(x^m)/(x^n)=x^(m-n)

=

9.
2 to 3
4(x-1)=15
to
4x-1=15
the distribuutive prperty
a(b-c)=ab-ac
what he did was
a(b-c)=ab-c
he did not distribute the 4 to the -1
4(x-1)+3=18
minus 3
4(x-1)=15
distribute 4 to x and -1
4x-4=15
add 4 to both sides
4x=19
divide by 4
x=19/4
3/4 = 9/12
You know you have 4 and 12 as your denominators. 4 x ? = 12
It's 3. 4 x 3 = 12 what you do to the bottom you do to the top, you multiplied x' 3
3 x 3 = 9
4 x 3 = 12
So, 3/4 is equal to 9/12
or 9 inches of 12 inches is equal to 3/4 of a foot.
Hope this helps. :)
