Answer 1

Hey friend...
Here is your answer

. We have to simply
[7 (81^1/4+256^1/4)1/4]^4 =?

Solution:-
[7 (81^1/4+256^1/4)1/4]⁴
= [7{(3⁴)^1/4 +(4⁴)^1/4} ×1/4]⁴
= [7(3+4)×1/4]⁴ = (7×7×1/4)⁴
= (49/4)⁴ = 49⁴/4⁴
= (5764801/256)
= 22518.8 approximate

I hope it will help you

Answer 2

7[ { (81)^1/4 + (256)^1/4 } ^1/4 ]^1/4
7[ { (3^4) ^ 1/4 + (4^4) ^ 1/4 }^1/4 ]1^4
7[ { 3+4} ^1/4 ] ^1/4
7 [ 7]^1/16
7 × 7^1/16
7^(1 + 1/16)
7^(17/16)
