k cho mk nha

36 . ( 146 + 57 ) + 64 . ( 143 + 57 )

= 36 . 146 + 57 + 64 . 143 + 57

= 36 . 146 + 143 + 57

= 36 . ( 146 + 143 + 1 )

= 36 . 290

= 10440

   143 + 35 + 57 + 65

= ( 143 + 57) + ( 35 + 65)

= 200 + 100

= 300

143+35+57+65

=(35+65)+(57+143)

=200+100

=300

=(143+57)+(35+65)

=200+100

=300

giúp mình với

\(57\cdot25+57:\frac{1}{35}+114\cdot20\)

\(=57\cdot25+57\cdot35+2\cdot57\cdot20\)

\(=57\cdot\left(25+35+2\cdot20\right)\)

\(=57\cdot\left(25+35+40\right)\)

\(=57\cdot100\)

\(=5700\)

\(=57.25+57.35+57.2.20\)

\(=57.\left(25+35+60\right)\)

\(=57.100=5700\)

bài 1) thực hiện phép tính

a) \(4^5-81:3^2=1024-9=1015\)

b) \(3^2.22-3^2.12=3^2.2\left(11-6\right)=18.5=90\)

c) \(2^3.15-\left[115-\left(12-5\right)\right]=120-\left(115-12+5\right)=120-115+12-5=12\)

d) \(3.3^2-19^{21}:19^{20}+2010^0=27-19+1=9\)

e)\(7^{25}:\left(7^{21}.46+7^{21}.3\right)=7^{25}:\left(7^{21}.49\right)=\frac{7^{21}.7^4}{7^{21}.49}=\frac{2401}{49}=49\)

bài 2)Tim x

a) 716 - (x - 143) = 695

<=> x - 143 = 716 - 695

<=> x - 143 = 21

<=> x = 21 + 143

<=> x = 164

vậy x = 164

57 + 469 + 374 + 531 + 426 + 143

\(=\left(57+143\right)+\left(469+531\right)+\left(374+426\right)\)

\(=200+1000+800=2000\)

9⁸ : 9⁶ - 2 . 2⁴ + 789⁰

^{\(=9^2-2^5+1\)}

^{\(=81-32+1=50\)}

chúc bạn học tốt

57+469+374+531+426+143
=(57+143)+(469+531)+(374+426)
=200+1000+800
=2000

9⁸:9⁶-2.2⁴+789⁰
=9²-2⁵+1
=81-31+1
=50+1
=21
Chúc hok tốt
nhớ k mk nha

\(57+469+374+531+143\)

\(=\left(57+143\right)+\left(469+531\right)+\left(374+426\right)\)

\(=200+1000+800=2000\)

\(9^8\div9^6-2.2^4+789^0\)

\(=9^2-2^5+1\)

\(=81-32+1\)

\(=\left(81+1\right)-32\)

\(=82-32=50\)
