Toán 2^7 : 2^2 + 5^4 : 5^3.2^4 – 3.2^5 ^7 = mũ 7 26/07/2021 By Harper 2^7 : 2^2 + 5^4 : 5^3.2^4 – 3.2^5 ^7 = mũ 7
$2^7 :2^2+ 5^4:5^3 .2^4 -3.2^5$ `=2^(7-2) + 5^(4-3) .2^4 -3.2^5` $=2^5+5.2^4-3.2^5$ `=5.2^4-2.2^5` `=5.2^4-2^6` `=2^4 ( 5-2^2)` $=2^4 . 1$ $=16$ Trả lời
Đáp án: Giải thích các bước giải: `2^7 : 2^2 + 5^4 : 5^3. 2^4 – 3.2^5` `=2^5+5^1. 2^4-3.32` `=32+5.16-96` `=16` Trả lời
$2^7 :2^2+ 5^4:5^3 .2^4 -3.2^5$
`=2^(7-2) + 5^(4-3) .2^4 -3.2^5`
$=2^5+5.2^4-3.2^5$
`=5.2^4-2.2^5`
`=5.2^4-2^6` `=2^4 ( 5-2^2)`
$=2^4 . 1$ $=16$
Đáp án:
Giải thích các bước giải:
`2^7 : 2^2 + 5^4 : 5^3. 2^4 – 3.2^5`
`=2^5+5^1. 2^4-3.32`
`=32+5.16-96`
`=16`
