Cześć ;-)
a)
[tex]110-5\cdot4=110-20=\boxed{90}\\\\(110-5)\cdot4=105\cdot4=\boxed{420}[/tex]
b)
[tex]2^2\cdot4+8=4\cdot4+8=16+8=\boxed{24}\\\\2^2\cdot(4+8)=4\cdot12=\boxed{48}[/tex]
c)
[tex](50+10)\cdot(7+3)=60\cdot10=\boxed{600}\\\\50+10\cdot7+3=50+70+3=\boxed{123}[/tex]
d)
[tex]400:(2+18)=400:20=\boxed{20}\\\\400:2+18=200+18=\boxed{218}[/tex]
e)
[tex]500-100\cdot5=500-500=\boxed0\\\\(500-100)\cdot5=400\cdot5=\boxed{2000}[/tex]
f)
[tex]600-100:4=600-25=\boxed{575}\\\\(600-100):4=500:4=\boxed{125}[/tex]
