Question

Calculeaza: a)|4|+|5|+|-11|. b)|-27|-|-13|+|16|. c)|-14|•|-2|-|-8|. d)|28|:|-14|+|8|. e)(|-2|)^8:(|2|)^6 -(|-2|)^2. f)(|5|-|2|)^2:|-3|-|-3|. (Va rog am nevoie de ea,e urgenttt)

Answer 1

Explicație pas cu pas:

$\bf a) \: |4| + |5| + | - 11| = \\ \bf 4 + 5 + 11 = \\ \bf 9 + 11 = \red{ \boxed{20} }$

$\bf b) \: | - 27| - | - 13| + |16| = \\ \bf 27 - 13 + 16 = \\ \bf 14 + 16 = \blue{ \boxed{30} }$

$\bf c) \: | - 14| \times | - 2| - | - 8| = \\ \bf 14 \times 2 - 8 = \\ \bf 28 - 8 = \green{ \boxed{20} }$

$\bf d) \: |28| \div | - 14| + |8| = \\ \bf 28 \div 14 + 8 = \\ \bf 2 + 8 = \pink{ \boxed{10} }$

$\bf e) \: {( | - 2|) }^{8} \div {( |2| )}^{6} - ( | - 2| )^{2} = \\ \bf {2}^{8} \div {2}^{6} - {2}^{2} = \\ \bf {2}^{8 - 6} - {2}^{2} = \\ \bf {2}^{2} - {2}^{2} = \orange{ \boxed{0} }$

$\bf f) \: ( |5| - |2| )^{2} \div | - 3| - | - 3| = \\ \bf (5 - 2)^{2} \div 3 - 3 = \\ \bf {3}^{2} \div 3 - 3 = \\ \bf 3 - 3 = \gray{ \boxed{0} }$
