Simplify the radical expression.

x^4y^9, the second option.

Step-by-step explanation:

A radical sign over an expression also means the expression is to the power of 1/2. In other words, the square root of n=n^1/2

(x^8y^18)^1/2

You divide the powers by 2

x^4y^9 is the answer

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
