Answer 1

$a)5 \times 5 \times 5 \times 5 \times 5 \times 5 \times 5 = {5}^{1} \times {5}^{1} \times {5}^{1} \times {5}^{1} \times {5}^{1} \times {5}^{1} \times {5}^{1} = {5}^{1 + 1 + 1 + 1 + 1 + 1 + 1} = {5}^{7}$

$b)73 \times 73 \times 73 \times 73 \times 73 \times 73 \times 73 = {73}^{1} \times {73}^{1} \times {73}^{1} \times {73}^{1} \times {73}^{1} \times {73}^{1} \times {73}^{1} = {73}^{1 + 1 + 1 + 1 + 1 + 1 + 1} = {73}^{7}$
