The expanded form of
\((y+5x)^{(1)/(2)}\) is
\((1)/(2) * y^{(1)/(2)} + (1)/(2) * (5x)^{(1)/(2)}\).

To expand the expression
\((y+5x)^{(1)/(2)}\), we can use the binomial expansion formula. The binomial expansion of
\((a+b)^n\) is given by:


\((a+b)^n = C(n,0) * a^n * b^0 + C(n,1) * a^(n-1) * b^1 + C(n,2) * a^(n-2) * b^2 + ... + C(n,n) * a^0 * b^n\)

Where
\(C(n, k)\) represents the binomial coefficient, which is given by
\(C(n, k) = (n!)/(k!(n-k)!)\).

In our case,
\(a = y\), \(b = 5x\), and
\(n = (1)/(2)\). We will expand it step by step:

Step 1: Calculate
\(C((1)/(2), 0)\)


\(C((1)/(2), 0) = ((1)/(2)!)/(0!((1)/(2)-0)!) = (1)/(2)\)

Step 2: Calculate
\(C((1)/(2), 1)\)


\(C((1)/(2), 1) = ((1)/(2)!)/(1!((1)/(2)-1)!) = ((1)/(2))/(1) = (1)/(2)\)

Now, we can use these coefficients to expand the expression:


\((y+5x)^{(1)/(2)} = (1)/(2) * y^{(1)/(2)} * (5x)^0 + (1)/(2) * y^0 * (5x)^{(1)/(2)}\)

Step 3: Simplify the terms with
\(5x\) and
\(y^0\):


\((1)/(2) * y^{(1)/(2)} * 1 + (1)/(2) * 1 * (5x)^{(1)/(2)}\)

Step 4: Further simplify the expression:


\((1)/(2) * y^{(1)/(2)} + (1)/(2) * (5x)^{(1)/(2)}\)

So, the answer is
\((1)/(2) * y^{(1)/(2)} + (1)/(2) * (5x)^{(1)/(2)}\).
