Question

if x is equal to bracket 4 minus root 15 (find the value of) x + 1 upon x ) ​

Answer 1

Explicação passo-a-passo:

We have:

x = 4 - √15

x^x+1 = ?

x^x . x^1

${x}^{x + 1} = {x}^{x} . {x}^{1}$

Then:

$( {4 - \sqrt{15} })^{4 - \sqrt{15}} .4 - \sqrt{15} \\ = ( {4 - \sqrt{15}})^{1 +4 - \sqrt{15} } \\ \\ = ( {4 - \sqrt{15} })^{5 - \sqrt{15} }$

it can be:

(4-√15)^5 - (4-√15)^-√15
