Question

What is the following sum? Assume x greater-than-or-equal-to 0 and y greater-than-or-equal-to 0 StartRoot x squared y cubed EndRoot + 2 StartRoot x cubed y Superscript 4 Baseline EndRoot + x y StartRoot y EndRoot

Answer 1

Answer:

Option b

Step-by-step explanation:

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

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