Apply Binomial Expansion Formula: To simplify the expression 4x5−y4)2weneedtoapplythebinomialexpansionformula$a−b)2=a2−2ab+b2where$a is 4x5 and b is y4.
Square 4x5: First, we square the term 4x5 to get (4x5)2=16x10.
Square y4: Next, we square the term y4 to get (y4)2=y8.
Multiply and Double: Then, we multiply the two terms together and double them to get the middle term of the binomial expansion, which is −2×(4x5)×(y4)=−8x5y4.
Combine All Terms: Now, we combine all the terms to get the fully simplified expression: 16x10−8x5y4+y8.
