Answer 1

Ответ:

Объяснение:

2⁵·2-4=2⁵⁺¹-2²=2⁶⁻2²=(2³-2)(2³+2)=(8-2)(8+2)=6·10=60

(1/7)⁻⁸·(1/7)⁷=7⁸·7⁻⁷=7⁸⁻⁷=7

3⁶÷3⁷=3⁶⁻⁷=3⁻¹=1/3

4⁻⁷÷4⁻¹⁰=4⁻⁷⁻⁽⁻¹⁰⁾=4⁻⁷⁺¹⁰=4³=64

(2⁻²)³=2^(-2·3)=2⁻⁶=1/2⁶=1/64

(0,1⁻²)⁴=0,1^(-2·4)=(1/10)⁻⁸=10⁸=100000000

-13·26⁻¹=-13/26=-1/2=-0,5

(1/9)⁻²+0,1⁻²=9² +(1/10)⁻²=9²+10²=81+100=181

81·3⁻⁵=3⁴⁺⁽⁻⁵⁾=3⁴⁻⁵=3⁻¹=1/3

5⁻⁶·5⁸÷125=5⁻⁶⁺⁸÷5³=5²⁻³=5⁻¹=1/5=0,2
