Question

find the value of A and B if 41 a + b 4 equal 512

Answer 1

By definition
1448=1⋅82+4⋅81+4⋅80=64+32+4=100,
and
121r=1⋅r2+2⋅r1+1⋅r0=r2+2r+1.
To find r, just solve the quadratic equation
r2+2r+1=100
by whatever method you find most convenient; the slickest method is probably to notice that r2+2r+1=(r+1)2, so (r+1)2=100=102.
