Question

if a+1 by a =4, what is the value of a⁴+1 by a⁴​

Answer 1

Answer:

if a+1 by a =4, what is the value of a⁴+1 by a⁴

answer 256

Answer 2

Given,

(a+1)/a = 4

To find,

(a⁴ + 1)/a⁴

Solution,

(a+1)/a = 4

a+1 = 4a

1 = 4a - a

1 = 3a

1/3 = a

So a = 1/3

(a⁴+1)/a⁴

((1/3)⁴ + 1⁴)/(1/3)⁴

(1/12 + 1)/(1/12)

((1+12)/12)/(1/12)

(13/12)/(1/12)

13/12 x 12

13

Hence (a⁴+1)/a⁴ is equal to 13
