Answer :-

7(x¹⁰+1)/x⁵

Used formulae:-

• (a+b)² = a²+2ab+b²
• (a-b)² = a²-2ab+b²
• (a/b)^m = a^m/b^m
• (x²⁰-1)² = (x²⁰)²-2(x²⁰)(1)+(1)²

=> x⁴⁰-2x²⁰+1

• (a^m)^n = a^(mn)
• (2x¹⁰)² = 2²(x¹⁰)² = 4x²⁰
• (x²⁰+1)² = (x²⁰)²+2(x²⁰)(1)+(1)²

=> x⁴⁰+2x²⁰+1

• x¹⁰ = (x⁵)²
• 49 = 7²
• (x¹⁰+1)² = (x¹⁰)²+2(x¹⁰)(1)+(1)²

=> x²⁰+2x¹⁰+1
