Simplify the given radical expression

What is the 6th root of 81a^4b^8?

Simplify: 3sqrt( 125)(5sqrt(5x^3y))

what is 3 square root of 2 + square root of 8

Simplify the expression: 54sqrt(125) / 9sqrt(5)

solve (sqrt 11 + sqrt5)/( sqrt11-sqrt5)

is equal to...

simplify. 2sqrt(8x)-sqrt(50x)

what is the answer to 2square root 18

square root of 2/5 all over 2

What is sqrt(12b^7)?

Subtract (2/(4 + sqrt(6))) - (2/(4 - sqrt(6)))

 



 



which simplifies to... 

simplify (7+10sqrt(3))/(1-sqrt(3))

 

Which simplifies to 

Simplify: radical 3 minus 5 divided by radical 3 plus 2

 

:)

Simplify: sqrt( 12 ) + sqrt(48)

Simplify √60*√12

 

:)

what is the square root of 8z^2 y^3
