Question

(2^38:2^30+6^23:6^23):[2^20*3^20+(2^14)^2]​

Answer 1

Răspuns:

Explicație pas cu pas:

(2³⁸:2³⁰ + 6²³:6²³):[2²⁰·3²⁰+(2¹⁴)²] =

= (2³⁸⁻³⁰ + 6²³⁻²³):[(2·3)²⁰ + 2¹⁴ˣ²] =

= (2⁸+6⁰):(6²⁰+2²⁸) = (2⁸+1):(6²⁰+2²⁸)

Un enunt mai corect ar fi fost :

(2³⁸:2³⁰ + 6²³:6³):[2²⁰·3²⁰+(2⁴)²] =

= (2³⁸⁻³⁰ + 6²³⁻³) :[(2·3)²⁰ + 2⁴ˣ²] =

=(2⁸+6²⁰):(6²⁰+2⁸) = 1
