Q. Assuming x and y are both positive, write the following expression in simplest radical form.7y336x6y5Answer:
Simplify Square Root of 36: Simplify the square root of 36.The square root of 36 is 6 because 62=36.
Simplify Square Root of x6: Simplify the square root of x6. Since x is positive and the exponent 6 is even, x6 is x6/2=x3.
Simplify Square Root of y5: Simplify the square root of y5. We can split y5 into y4⋅y1. The square root of y4 is y24=y2, and the square root of y1 remains under the radical as y.
Combine Simplified Parts: Combine the simplified parts outside the radical.We have 7y3×6×x3×y2 from the previous steps.Multiplying these together gives us 42y3×x3×y2.
Combine Like Terms: Combine the like terms.y3×y2 can be combined by adding the exponents since they have the same base.This gives us y3+2=y5.So, we have 42×x3×y5.
Combine Simplified Parts Inside Radical: Combine the simplified parts inside the radical. We are left with y inside the radical.
Write Final Expression: Write the final expression.The final expression is 42x3y5y.
