Apply Binomial Expansion: Apply the binomial expansion to the expression (3x4+y5)2. When we square a binomial, we use the formula (a+b)2=a2+2ab+b2, where a is the first term and b is the second term. In this case, a=3x4 and b=y5.
Square First Term: Square the first term (3x4)2.(3x4)2=32×(x4)2=9x8
Multiply and Double: Multiply the two terms together and double the result, 2×(3x4)×(y5).2×(3x4)×(y5)=2×3×x4×y5=6x4y5
Square Second Term: Square the second term (y5)2.(y5)2=(y5)×(y5)=y10
Combine Results: Combine the results from steps 2, 3, and 4 to get the final simplified expression.9x8+6x4y5+y10
