Q. Given x>0 and y>0, select the expression that is equivalent to3216x12y872x4y3872x41y836x41y836x4y38
Identify Cube Root: Identify the cube root of the given expression.The cube root of a product is the product of the cube roots of each factor.So, we need to find the cube root of 216, x12, and y8 separately.
Simplify 216: Simplify the cube root of 216. 216 is a perfect cube because 216=63. Therefore, the cube root of 216 is 6.
Simplify x12: Simplify the cube root of x12. The exponent rule for roots states that nam=anm. Applying this rule, we get 3x12=x312=x4.
Simplify y8: Simplify the cube root of y8. Using the same exponent rule, we get 3y8=y38.
Combine Simplified Roots: Combine the simplified cube roots.We have the cube root of 216 as 6, x12 as x4, and y8 as y8/3.Multiplying these together gives us 6x4y8/3.
Compare with Options: Compare the result with the given options.The expression 6x4y(8/3) matches one of the given options.
