Question

solve this for 100 points​

Answer 1

Answer:

3

Step-by-step explanation:

formula --->

____________

a^m ÷ a^n= a^(m-n)

now

3^(-4)÷ 3^(-5)

1

=3^(-4) × ______

3^(-5)

= 3^ {-4-(-5)}

= 3^ (-4+5)

= 3^1

=3

__________________________________

1. a^m a^n=a^(m+n)

2.( a^m)^n=a^mn

3. a^(-m) =1/a^m

Answer 2

Answer:

${3}^{ - 4} \div {3}^{ - 5}$

$= {3}^{( - 4) - ( - 5)}$

$= {3}^{ - 4 + 5}$

$= {3}^{1}$

$= 3$
