Answer 1

Ответ:

a)4^11 * 4^9 = 4^(11-9)=4^2=16

б)6^(-5) :6^(-3) = 6^(-5-(-3))= 6^(-2)=1/36

в)(2^(-2))^3=2^(-2*3)=2^(-6)=1/64

Answer 2

Ответ:

a)

${4}^{11} \times {4}^{ - 9} = {4}^{11 + ( - 9)} = {4}^{2} = 16$

б)

${6}^{ - 5} \div {6}^{ - 3} = {6}^{ - 5 - ( - 3)} = {6}^{ - 2} = \frac{1}{36}$

в)

$( {2}^{ - 2}) {}^{3} = {2}^{ - 2 \times 3} = {2}^{ - 6} = \frac{1}{64}$
