Question

Me ajudar por favor

2⁻⁹÷2²=

[(14,9)¹⁵]²=

(1,1).(1,1)⁻³.(1,1)⁻²=

( 1 )¹³ ÷( 1 )¹¹ =
10 11

[10⁻⁴]³ =

(0,5)⁴÷ 0,5²=

Answer 1

${2}^{ - 9} \div {2}^{2} = {2}^{ - 9} \times {2}^{ - 2} = {2}^{ - 11} = {( \frac{1}{2}) }^{11}$

${ ({(14.9)}^{15}) }^{2} = {(14.9)}^{30}$

$(1.1) \times {(1.1)}^{ - 3} \times {(1.1)}^{ - 2} = {(1.1)}^{ - 4} = { (\frac{1}{1.1} )}^{4}$

${(1)}^{13} \div {(1)}^{11} = {(1)}^{13} \times {(1)}^{ - 11} = {(1)}^{2} = 1$

${ ({10}^{ - 4}) }^{3} = {10}^{ - 12} = {( \frac{1}{10}) }^{12}$

${(0.5)}^{4} \div {(0.5)}^{2} = {(0.5)}^{4} \times {(0.5)}^{ - 2} = {(0.5)}^{2}$
