Question

3⁴:[2⁷-(4×5⁵:20-5³):2²]=? va rog ajutati mă!! rapid!​

Answer 1

$3^4:[2^7-(4\cdot 5^5 : 20 - 5^3):2^2]=$

$3^4:[2^7-(\frac{4 \cdot 5^5}{20}- 5^3):2^2]=$

$3^4:[2^7-(\frac{ 5^5}{5}- 5^3):2^2]=$

$3^4:[2^7-({5^4- 5^3):2^2]=$

$3^4:[2^7-({5^{1+3}-5^3):2^2]=$

$3^4:[2^7-({5 \cdot 5^3-5^3):2^2]=$

$3^4:[2^7-(({5 -1)\cdot5^3):2^2]=$

$3^4:(2^7-4\cdot5^3:2^2)=$

$3^4:(2^7-2^2\cdot5^3:2^2)=$

$3^4:(2^7-1\cdot5^3)=$

$\frac{3^4}{2^7-1\cdot5^3} =$

$\frac{81}{128-1\cdot125} =$

$\frac{81}{128-125} =$

$\frac{81}{3} =27$
