Given Values: We are given:x=8y=2Expression = y4x2Identify the expression after substituting the value of x and y.Substitute 8 for x and 2 for y in y4x2.y=20
Substitute Values: Calculate the value of x squared, which is 8 squared.82=8×8=64
Calculate x2: Calculate the value of y to the power of 4, which is 2 to the power of 4.24=2×2×2×2=16
Calculate y to the power of 4: Divide x squared by y to the power of 4.1664=4
