Final answer:
The value of x²y¹ when x=10 and y=5 is 500.
Step-by-step explanation:
The question asks for the value of x²y¹ when y=5 and x=10.
To find this, we simply substitute the given values into the expression.
Substituting these values in, we get:
10² * 5¹ = (10 * 10) * 5 = 100 * 5 = 500.
Therefore, the value of x²y¹ when x=10 and y=5 is 500.
