Answer:
(7[tex]x^{8}[/tex] -4[tex]y^{32}[/tex] )(7[tex]x^{8}[/tex] + 4[tex]y^{32}[/tex] )
Step-by-step explanation:
49[tex]x^{16}[/tex] - 16[tex]y^{64}[/tex] ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
49[tex]x^{16}[/tex] - 16[tex]y^{64}[/tex]
=(7[tex]x^{8}[/tex] )² - (4[tex]y^{32}[/tex] )²
= (7[tex]x^{8}[/tex] - 4[tex]y^{32}[/tex] )(7[tex]x^{8}[/tex] + 4[tex]y^{32}[/tex] )
