Answer 1

Step-by-step explanation:

$( {3}^{ - 7} \div {3}^{ - 10} ) \times {3}^{ - 15} \\ \\ ( {3}^{ - 7} \times {3}^{ 10} ) \times {3}^{ - 15} \\ \\ {3}^{ - 7 + 10} \times {3}^{ - 15} \\ {3}^{3} \times {3}^{- 15} \\ {3}^{ - 12} \\ \frac{1}{ {3}^{12} } \\ \frac{1}{531441}$

${2}^{ - 3} \times { - 7}^{ - 3} \\ {(2 \times - 7)}^{ - 3} \\ { - 14}^{ - 3} \\ \frac{ - 1}{ {14}^{3} } \\ \frac{ - 1}{2744}$

${3}^{ - 5} \times {10}^{ - 5} \times 125 \\ {3}^{ - 5} \times {(2 \times 5)}^{ - 5} \times {5}^{3} \\ {6}^{ - 5} \times {5}^{ - 2} \\ \frac{1}{ {6}^{5} \times {5}^{2} } \\ \frac{1}{194400}$

${( { (\frac{1}{2} )}^{ - 1} - { (\frac{1}{5} )}^{ - 1}) }^{ - 1} \\ {(2 - 5)}^{ - 1} \\ {( - 3)}^{ - 1} \\ \frac{ - 1}{3}$

16+27+16 = 59

$( { \frac{5}{4}) }^{4} \\ \frac{625}{256}$

m -(-3)= 5

m + 3 = 5

m = 2

$\frac{1}{0.1} = \frac{1}{ \frac{1}{10} } = 10$

x -(-3)= 5

x + 3 = 5

x = 2
