Question

(123456789)(79543211) + (23456789)² then number of zeroes in x¼ is

Answer 1

x = (123456789)(79543211) + (23456789)²
x = (100000000 + 23456789) (76543211) + (23456789)²
x = 100000000 × 76543211 + (23456789) × (76543211) + (23456789)²
x = 100000000 × 76543211 + (23456789) [76543211 + 23456789]
x = 100000000 [76543211 + 23456789]
x = 100000000 [100000000]
x = 10^8 × 10^8
= 10^16

x^¼ = (10^16)^¼
= 10⁴
= 10000

Number of zeroes = 4
