Write each expression as an equivalent expression with a single logarithm. Assume xx, yy, and zz are positive real
Alekssandra [29.7K]

Answer:

\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}

Step-by-step explanation:

Given:

1/2(ln(xx + yy) − ln(zz))

Now,

From the properties of log function,

1)  n × ln(x) = ln(xⁿ)

and,

2)  ln(A) - ln(B) = \ln\frac{A}{B}

applying the properties in the given equation

we get the above equation as:

\frac{1}{2}(\ln\frac{xx + yy}{zz})        

( using the property 2 we get (ln(xx + yy) − ln(zz) = \ln\frac{xx + yy}{zz}  

or

⇒ \ln(\frac{xx + yy}{zz})^{\frac{1}{2}}    ( using the property 1 i.e n × ln(x) = ln(xⁿ) )

expression as an equivalent expression with a single logarithm is \ln(\frac{xx + yy}{zz})^{\frac{1}{2}}

Lelechka [254]
1 3/4 hours of work equates to $18.375 so $18.38.

2 1/3 hours of work equates to $24.50.

1 5/12 hours of work equates to $14.875 so $14.88

Add all values $18.38+$24.50+$14.88 = $57.76

Doug has a total amount of earnings which = $57.76, good luck!
