What is the following sum? Assume x > 0 and y > 0 sqrt x^2y^2+2 sqrt x^3y^4+xy sqrt y
Gwar [14]

Answer:

xy(1+2y\sqrt{x}+\sqrt{y})

Step-by-step explanation:

Given expression,

\sqrt{x^2y^2}+2\sqrt{x^3y^4}+xy\sqrt{y}

=(x^2y^2)^\frac{1}{2} + 2(x^3y^4)^\frac{1}{2} + xy\sqrt{y}

\because (\sqrt{x}=x^\frac{1}{2})

=(x^2)^\frac{1}{2} (y^2)^\frac{1}{2} + 2(x^3)^\frac{1}{2} (y^4)^\frac{1}{2} + xy\sqrt{y}

(\because (ab)^n=a^n b^n)

=x^{2\times \frac{1}{2}} y^{2\times \frac{1}{2}} + 2(x^{3\times \frac{1}{2}})(y^{4\times \frac{1}{2}})+xy\sqrt{y}

\because (a^n)^m=a^{mn}

=x^1 y^1 + 2x^{1\frac{1}{2}} y^2 + xy\sqrt{y}

=xy+2x.(x)^\frac{1}{2} y^2 + xy\sqrt{y}

=xy+2xy^2\sqrt{x}+xy\sqrt{y}

=xy(1+2y\sqrt{x}+\sqrt{y})

Help will mark brainiest
Kitty [74]

Answer:

original price =148.57

Step-by-step explanation:

The original price * discount  is the markdown

original price - discount = sale price

original price - original price * discount = sale price

Factor out the original price

original price (1-discount) = sale price

We know the discount is 65% and the sale price is 52

original price (1-.65) = 52

original price (.35) = 52

Divide by .35 on each side

original price (.35)/.35 = 52/.35

original price =148.57
