Question

28√x+1426=3\4(2872) find the value of x satisfying

Answer 1

28root x= 3/4 *2872-1426
= 3*718-1426
=2154-1426
= 728
rootx= 728/28= 104/4= 26
x= 26*26= 676

Answer 2

Let the unknown number be x

28√x  + 1426 = 3/4 of 2872

28√x  + 1426 = 3/4  *  2872

28√x  + 1426 = 2154

28√x = 2154 - 1426

28√x = 728

√x = 728/28

√x = 26

x = 26²

x = 26 * 26

x = 676

Verification =

28√676 + 1426

= 28(26) + 1426

= 728 + 1426

= 2154

= 2872 * 3/4

=3/4 of 2872
