Answer 1

Răspuns:

$d) {2}^{7} - {3}^{4} = 128 - 81 = 47 \\ e) {4}^{3} - {1}^{20} = 64 - 1 = 63 \\ f) {7}^{3} - {4}^{4} = 343 - 256 = 87 \\ g) {15}^{2} - {0}^{9} = 225 - 0 = 225 \\ h) {2}^{4} - {4}^{2} = 16 - 16 = 0 \\ i) {2}^{3} \times {5}^{3} = (2 \times 5) {}^{3} = {10}^{3} \\ j) {5}^{2} \times {2}^{4} = 25 \times 16 = 400 \\ k) {7}^{2} \div 5 = 49 \div 5 = 9.8 \\ l) {18}^{2} \div {3}^{4} = 324 \div 81 = 4$

sper că te-am ajutat!!

Answer 2

d) = 128 - 81

e) = 64 - 1

f) = 343-256

g) = 225 - 0

h) = 16 - 16

i) = 8 · 125

j) = 25· 16

k) = 49 :5

l) = 324 : 81
