Answer 1

Hola!

Explicación paso a paso:

a)

$6. {( - 1)}^{3} - {3}^{2} .2 \div \sqrt{ {6}^{2} } \\ 6.( - 1) - 9.2 \div 6 \\ - 6 - 18 \div 3 \\ - 6 - 6 \\ - 12$

b)

${(4 - 3)}^{2} - 5.( {2}^{2} - 7) \\ {(1)}^{2} - 5.(4 - 7) \\ 1 - 5.( - 3) \\ 1 - ( - 15) \\ 1 + 15 \\ 16$

c)

${[( \sqrt{9} - \sqrt{25}) ]}^{5} \\ [(3 - 5)]^{2} \\ {[( - 2)]}^{2} \\ 4$

d)

${5}^{2} .( \sqrt{64} + 8 \div 2) \\ 25.(8 + 4) \\ 25.(12) \\ 300$

e)

$( {9}^{2} - {7}^{2} ) \div \sqrt{64} \\ (81 - 49) \div 8 \\ (32) \div 8 \\ 4$

f)

${( - \sqrt{49} + {3}^{4} \div {3}^{2} )}^{5} \\ {( - 7 + 81 \div 9)}^{5} \\ {( - 7 + 9)}^{5} \\ {2}^{5} \\ 32$
