​

Answer 1

Answer:

$(4 9{x}^{2} - 25 {y}^{2} )(49 { x}^{2} + 25 {y}^{2} ) \\( 49 {x}^{2} {)}^{2} - (25 {y}^{2} {)}^{2} \\ \\ 2401 {x}^{4} - 625 {y}^{4} answer of \: this \: \:$

I hope you understand from this

Answer 2

Answer:

(7x-5y)(7x+5y)(49x²+25y²)

= {(7x)²-(5y)²}(49x²+25y²)

=(49x²-25y²)(49x²+25y²)

=(49x²)²-(25y²)²

=2401x⁴-625y⁴
