Answer 1

Ответ:

2.

1)

${x}^{9} \times {x}^{2} = {x}^{9 + 2} = {x}^{11}$

2)

$a {a}^{7} = {a}^{1} {a}^{7} = {a}^{8}$

3)

${b}^{3} \times {b}^{3} = {b}^{3 + 3} = {b}^{6}$

4)

${a}^{23} \div {a}^{17} = {a}^{23 - 17} = {a}^{6}$

5)

$( {y}^{4} ) ^{3} = {y}^{4 \times 3} = {y}^{12}$

6)

$(( {a}^{7} ) ^{3} ) ^{2} = {a}^{7 \times 3 \times 2} = {a}^{42}$

7)

$( {a}^{6} ) ^{3} \times ( {a}^{2} ) ^{4} = {a}^{6 \times 4} \times {a}^{2 \times 4} = {a}^{24} \times {a}^{8} = {a}^{24 + 8} = {a}^{32}$

3.

1)

${2}^{2} \times {2}^{3} = {2}^{2 + 3} = {2}^{5} = 32$

2)

${3}^{15} \div {3}^{11} = {3}^{15 - 11} = {3}^{4} = 81$

3)

${5}^{9} \times {5}^{3} \div {5}^{10} = {5}^{9 + 3 - 10} = {5}^{12 - 10} = {5}^{2} = 25$

4)

${2}^{24} \div ( {2}^{8} ) ^{2} = {2}^{24} \div {2}^{8 \times 2} = {2}^{24} \div {2}^{16} = {2}^{24 - 16} = {2}^{8} = 256$

5)

$( {11}^{3} ) ^{4} \div ( {11}^{5} ) ^{2} = {11}^{3 \times 4} \div {11}^{5 \times 2} = {11}^{12} \div {11}^{10} = {11}^{12 - 10} = {11}^{2} = 121$
