Estimate the quotient and verify by actual calculation:
2758÷96
Step-1: Estimating quotient:
2758 is rounded off as 2800.
96 is rounded off as 100.
Thus, 2800÷100=28
Step-2: Verification:
96282758192----838768---70
Thus, quotient is 28 and remainder is 70.
Hence verified.
By actual division, find the quotient and the remainder when (x4+1) is divided by (x - 1). Verify that remainder = f(1).
