Answer 1

Explicație pas cu pas:

$3. \\ a)5 \times 5 \times 5 \times 5 \times 5 \times 5 = {5}^{6} \\ b)12 \times 12 \times 12 = {12}^{3} \\ c)7 \times 7 \times 7 \times 7 \times 7 = {7}^{5} \\ d)8 \times 3 \times 8 \times 3 \times 8 \times 3 \times 8 \times 3 = {8}^{4} \times {3}^{4} \\ e)1 \times 1 \times 1 \times 1 \times 1 = {1}^{5} \\ f)3 \times 3 \times 3 \times .... \times 3 = {3}^{2017 } \\ \\ 4. \\ a) {0}^{5} + {5}^{0} = 0 + 1 = 1 \\ b) {5}^{3} + {7}^{0} = 125 + 1 = 126 \\ c) {1}^{200} + {0}^{200} + {6}^{3} = 1 + 0 + 216 = 217 \\ d) {2}^{7} - {3}^{4} = 128 - 81 = 47 \\ e) {4}^{3} - {1}^{20} = 64 - 1 = 63 \\ f) {7}^{3} - {4}^{4} = 343 - 256 = 87 \\ g) {15}^{2} \times {0}^{9} = 225 \times 0 = 0 \\ h) {2}^{4} \div {4}^{2} = 16 \div 16 = 1 \\ i) {2}^{3} \times {5}^{3} = (2 \times 5) {}^{3} = {10}^{3} = 1000 \\ j) {5}^{2} \times {2}^{4} = 25 \times 16 = 400 \\ k) {7}^{2} \div {5}^{0} = 49 \div 1 = 49 \\ l) {18}^{2} \div {3}^{4} = 324 \div 81 = 4$
