Answer 1

Step-by-step explanation:

26/144=91/81=63/324=39/x

26*81/144*91=63/324=39/x

26*81*324/144*91*63=39/x

26*81*324*x/144*91*63*39

Answer 2

Given $26:144::91:81::63:324::39:?$

Consider $26:144$

Observing, $26\rightarrow 2\times 6=12\rightarrow 12^{2}=144$

Similarly considering $91:81$

Observing, $91\rightarrow 9\times 1=9\rightarrow 9^{2}=81$

Similarly considering $63:324$

Observing, $63\rightarrow62\times 3=18\rightarrow 18^{2}=324$

Considering, $39:?$

Observing, $39\rightarrow 3\times 9=27\rightarrow 27^{2}=729$
