Question

(3¹⁵*4+5*3¹⁵)/3¹⁶

Answer 1

\(\frac{3^{15}.4+5.3^{15}}{3^{16}}=\frac{3^{15}.\left(4+5\right)}{3^{16}}=\frac{3^{15}.3^2}{3^{16}}\)

= 3

Answer 2

\(\left(3^{15}.4+5.3^{15}\right):3^{16}\\ =[3^{15}(4+5)]:3^{16}\\ =129140163:43046721\\ =3\)

Answer 3

(3¹⁵. 4 + 5. 3¹⁵):3¹⁶

=[3¹⁵. (4+5)]:3¹⁶

=[3¹⁵. 9]: 3¹⁶

=[3¹⁵. 3²]:3¹⁶

=\(\frac{3^{15}.3^2}{3^{16}}=\frac{3^2}{3}=\frac{9}{3}=3\)
