Question

How do you simplify the equation below?

Answer 1

\[\sqrt{27x ^{2}y} - \sqrt{45xy ^{2}} + \sqrt{108x ^{2}y} - \sqrt{125xy ^{2}}\]

Answer 2

take the square root of each term

Answer 3

How..

Answer 4

\[\sqrt{27}\] is how much??

Answer 5

5.196152423

Answer 6

you can simplify by looking for squares inside the radicals

\[\sqrt{27x^2y} = \sqrt{9}\times \sqrt{3}\times \sqrt{x^2}\times \sqrt{y}\]

can you simplify this

Answer 7

Is is \[\sqrt{135x ^{2}y}-\sqrt{170xy ^{2}}\]??

Answer 8

@campbell_st?

Answer 9

\[\sqrt{27x^2y} = 9x \sqrt{3y}\]

Answer 10

you will need similar simplifications for

\[\sqrt{45xY^2} = \sqrt{9}\times \sqrt{y^2}\times \sqrt{5x}\]

\[\sqrt{108x^2 y} = \sqrt{36}\times \sqrt{x^2}\times \sqrt{3y}\]

\[\sqrt{125xy^2} = \sqrt{25} \times \sqrt{y^2} \times \sqrt{5x}\]
