False.
Only log(x^2)=2log(x)
For example, let x=10
(log(10))^2=1^2=1
yet 2log(10)=2*1=2

Show work for this fraction 1 2/3-3/4
statuscvo [17]
1\frac23-\frac34

Write 1 2/3 as an improper fraction...
1 = 3/3. Plus the 2/3 makes 5/3.

\frac53-\frac34

To add/subtract fractions, they need the same denominator. (bottom number)

We can change the denominator by multiplying the top and bottom of a fraction by the same number. (it will stay equal, like 1/2 and 2/4)

Let's change 5/3 and 3/4 to a denominator of 12.

5/3 = 20/12 (bottom multiplies by 4, so does the top)
3/4 = 9/12 (bottom multiplies by 3, so does the top)

\frac{20}{12}-\frac9{12}

Now we just subtract the 20 minus 9 twelfths. (the twelfths act as a sort of unit)

\boxed{\frac{11}{12}}
