please help[ someone]

Answer 1

i know i have to substitute x from 82 but the power on both side is the problem @SharpEdge

Answer 2

can u show the work pls

Answer 3

hmm its 82 not 81

Answer 4

k

Answer 5

raise to the power of sqrt x on both sides, so that you are only left with
f(x^2+1) on left,
right side = \(\large x^{\dfrac{6\sqrt x}{x}}=x^{\dfrac{6}{\sqrt x}}\)
now to get , f(82) , from f(x^2+1), just plug in x=9

Answer 6

so, \(\huge f(9^2+1)=f(82)=9^{\dfrac{6}{\sqrt9}}=...?\)

simplify.....
