2.-71+8×25-(-46)=
3. 144:(-4)-14×(-5)=
4.(282+118):16+(-213)
tolong jawab soalnya bsk di kumpulin
[tex]1. \: \:( 45 \times ( - 115) )\div 15 \\ - 5.175 \div 15 \\ - 345[/tex]
[tex]2. \: \: - 71 + 8 \times 25 - ( - 46 \\ - 71 + (8 \times 25) + 46 \\( - 71 + 200) + 46 \\ 129 + 46 \\ 175[/tex]
[tex]3. \: \:( 144 \div ( - 4)) - 14 \times ( - 5) \\ - 36 - (14 \times ( - 5)) \\ - 36 - ( - 70) \\ - 36 + 70 \\ 34[/tex]
[tex]4. \: \: (282 + 118) \div 16 + ( - 213) \\ (282 + 118) \div 16 - 213 \\( 400 \div 16) - 213 \\ 25 - 213 \\ - 188[/tex]
Semoga membantu
Jawaban:
1. 45×(-115):15 = (45×(-115)):15
=(-5.175) : 15
= (-345)
2. -71+8×25-(-46)= -71+(8×25)-(-46)
= -71+200-(-46)
= 129-(-46)
= 129+46
= 175
3. 144:(-4)-14×(-5) = (144:(-4)-14×(-5)
= -36-(14×(-5))
= -36-(-70)
= 34
4.(282+118):16+(-213)= (400:16)+(-213)
=25+(-213)
= - 188
