Answer 1

Resposta:

$a)>18_5+9+11-22=18_5-2\\\\b)>200+150_120+180\:=20\cdot \:150_1+380\\\\c)>\left(-5\right)_{\left(-3\right)}+\left(-2\right)_{\left(11\right)}=\left(-5\right)_{-3}+\left(-2\right)_{11}\\\\d)>-5+2_{-4}+2_5+2=2_5+2_{-4}-3\\\\e)>-6+3_{-4}+2_5+10=4+2_5+3_{-4}\\\\f)>\left(-5\right)_{\left(-3\right)}+\left(-2\right)_{\left(-11\right)}=\left(-5\right)_{-3}+\left(-2\right)_{-11}\\\\g)> \:\left(-12\right)+\left(+10\right)_{\left(-8\right)}+\left(-15\right)=10_{-8}-27$

$h)>\left(-20\right)_{\left(22\right)}+\left(30\right)_{\left(8\right)}=\left(-20\right)_{22}+30_8$
