Apply Power to Terms: Apply the power to each term inside the parentheses.When raising a binomial to the power of 2, we square each term and also include the cross-product term, which is 2 times the product of the two terms. So, (a−b)2=a2−2ab+b2.In this case, a=4x5 and b=y5.Therefore, (4x5−y5)2=(4x5)2−2×(4x5)×(y5)+(y5)2.
Calculate Each Term: Calculate each term separately.(4x5)2=16x10 (since (42)⋅(x5)2=16x10),−2⋅(4x5)⋅(y5)=−8x5y5 (since 2⋅4⋅x5⋅y5=8x5y5),(y5)2=y10 (since (y5)2=y10).
Combine Results: Combine the results from Step 2.The fully simplified form of the expression is 16x10−8x5y5+y10.
