Question

4. Calculati: a) 14 + 2 + 32, d) 73 – 07 + 27 - 70, b) 2° +2° +22 + 2 + 24, e) 62 +7 +82-92; c) 0 + 5° +1; f) 132 - 122 + 112-10- -​

Answer 1

Răspuns:

2 la puterea zero este 1

4).14+2+32=58

b).1+1+22+2+24=24+26=50

d).73-0+27-70=100-70=30

e).62+7+82-92=69+82-92=151 -92=59

c).0+5^0+1=0+1 +1=2

f).13 (la puterea 2)-12(la puterea 2)+11( la puterea 2)-10( la puterea 2) =

= (13×13)-(12×12)+(11×11)-(10×10)=

169 -144+121 -100=

=290-244= 46

a). 1+8+9=18

b).1+2+4+8+16=15+16=31

c).0+1+(1×1×1)=1+1=2

d).49-0+128 -1=176

e).36+49+84-81= 179-81= 88

f).(13×13)-(12+12)+(11×11)-(10×10)=

=25+(121-100)= 46
