Question

Mă ajută cineva? 3×(n-8^13:4^17)=81^8:27^9​

Answer 1

Bună! ⭐

_________

$3*(n-8^{13} :4^{17} )=81^{8} :27^{9} <=>$

$<=> 3*[n-(2^{3} )^{13}: (2^{2})^{17}]=(3^{4} )^{8} :(3^{3} )^{9} <=>$

$<=>3*(n-2^{39} :2^{34} )=3^{32} :3^{27} <=>$

$<=> 3*(n-2^{39-34} )=3^{32-27} <=>$

$<=> 3*(n-2^{5} )=3^{5} <=>$

$<=> 3*(n-32)=3^{5} /:3 <=>$

$<=> n-32=3^{4} <=> n=81+32 =>\\\\=>n=113$
