$\frac{1}{4}$$\log (x^2+y^2)$

Work Step by Step

$Expand$ $the$ $expression$: $\log \sqrt[4]{x^2+y^2}$ Rewrite the fourth root $\log (x^2+y^2)^\frac{1}{4}$ Apply the Third Law of Logarithms $\log (x^2+y^2)^\frac{1}{4}$ = $\frac{1}{4}$$\log (x^2+y^2)$ You cannot take out the squares on x and y since x and y are being added $\frac{1}{4}$$\log (x^2+y^2)$
