đáp số là 4450 nhak bạn

89 *16 - 89 * 25 +89 * 59

= 89 * (16 - 25 + 59) 

= 89 * 50

= 98 * 100 : 2

= 9800 : 2

= 4900

89 x 16 - 89 x 25 + 89 x 59

= 89 x ( 16 - 25 + 59 )

= 89 x 50

= 4450

\(89.16-89.25+89.59\)

\(=89.\left(16-25+29\right)\)

\(=89.50\)

\(=4450\)

Đáp án :

89 x 89 =8722

7 + 16 =23

154 +89 =243

21 + 89 + 16 - 65 + 89 + 99 + 10087 + 7647 x 0 = 10336

  21 + 89 +16 - 65 + 89 + 99 + 10087 + 7647 x 0 

=  21 + 89 +16 - 65 + 89 + 99 +10087+ 0

= 110 + 16 - 65 + 89 + 99 +10087+ 0

= 126 - 65 + 89 + 99 +10087+ 0

= 61 + 89 + 99 +10087+ 0

= 150 + 99 +10087+ 0

= 249 +10087+ 0

= 10336 + 0

= 10336.

a: \(-177-\left\lbrack89+\left(-177\right)+75\right\rbrack-\left(-25\right)\)

=-177-[89-177+75]+25

=-177-89+177-75+25

=-89-50

=-139

b: \(2\cdot\left\lbrack16+\left(-12\right)-5\right\rbrack+\left(-32\right)-\left(-10\right)\)

\(=2\cdot\left\lbrack16-17\right\rbrack-32+10\)

=2*(-1)-32+10

=-34+10

=-24

c: \(56\cdot53-\left\lbrack57+\left(-75\right)-\left(-9\right)\cdot2\right\rbrack\)

=2968-[57-75+18]

=2968

d: \(16\cdot\left(-45\right)+16\cdot34-\left(-16\right)\cdot\left(-89\right)\)

\(=16\left(-45+34\right)-16\cdot89\)

\(=16\left(-11-89\right)=16\cdot\left(-100\right)=-1600\)

e: \(77\cdot18-\left(-77\right)\cdot60+\left(-77\right)\cdot\left(-22\right)\)

\(=77\cdot18+77\cdot60+77\cdot22\)

\(=77\left(18+60+22\right)=77\cdot100=7700\)

89/16+25(9/16÷125/64)÷(-27/8)

= \(\frac{89}{16}+25\left(\frac{9}{16}:\frac{125}{64}\right):-\frac{27}{8}\)

=\(\frac{89}{16}+\frac{25.36}{125}:-\frac{27}{8}\)

=\(\frac{89}{16}-\frac{32}{15}=\frac{823}{240}\)

\(\frac{89}{16}+25.\left(\frac{9}{16}:\frac{125}{64}\right):\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+25.\frac{36}{125}:\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+\frac{36}{5}:\left(\frac{-27}{8}\right)\)

=\(\frac{89}{16}+\left(\frac{-32}{15}\right)\)

=\(\frac{823}{240}\)

98+45+99+16+1999999999=2000000257

x+16=89

      x=89-16

      x=73

x + 16 = 89

x         = 89 - 16 

x         = 73
