Question

Calculati: a) 7 - 32:2 la puterea a 3 a

b) 4 + 2 X 5 la puterea a 2 a

c) (7 la puterea a 2 a - 6X8) la puterea a 10 a

d) 2 la puterea a 6 a X 34 - 2 la puterea a 6 a X 84+2 la puterea a 6 a X 51​

Answer 1

Răspuns:

Explicație pas cu pas:

a) 7-32:$2^{3}$ = 7-$2^{5} + 2^{3}$ = 7-$2^{2}$ = 7-4 = 3

b) 4+2*$5^{2}$ = 4+2*25 = 4+50 = 54

c) $( 7^{2}-6*8)^{10}$ =  $(49-48)^{10}$ = $1^{10}$ = 1

d) $2^{6}*34-2^{6}*84+2^{6}*51$ = $(34-84+51)*2^{6}$ = $1*2^{6}$ = $2^{6}$ = 64
