Question

2. Efectuați: a) 10² [4+5.3²-25 +4³ (49-32): 2³];
b) [(26)4:2³ (26+26)-46:2¹0]: (228-22)+9.

coroana + 20 stele
repde si corect!!​

Answer 1

a)

$100(4+(\frac{53}{10}) ^{2} - 25+2^6*17:2^{3}\\100(4+(\frac{53}{10})^{2} - 25+2^{3} * 17\\100(4+(\frac{53}{10})^{2}-25+136\\ 11500+100*(\frac{53}{10})^{2} \\11500+2809\\=14309$

b)

$(26*2^{2} :2^{3} *52-46:2*0):206+9\\(\frac{26*2^{2} }{2^{3}})*52-0):206+9\\(\frac{26}{2} * 52) :206+9\\(13*52):206+9\\\frac{676}{206} +9\\=\frac{1265}{103\\}$
