a calculator gives 1.04 rounded to 2 decimal places
by hand you may just want to round off the 1.028/10.74 as 1/10 or .1. square it to get 1/100
add 1 to get 1.01. square it to get 1.0201 square that to get the 4th power of 1.01 which gives close a little over 1.03. That's close to the calculator result of 1.04
