Answer:
he gained 2,100
Step-by-step explanation:
The answer is: " 5⁻ ⁵⁰ " .
__________________________________________
Note that: |7-9| = <span>| -2 | = 2 .
__________________________________________
Note: 5</span>³ * 5⁻⁵ = 5⁽ ⁽³⁾ ⁺ ⁽⁻⁵⁾ ⁾ = 5⁽³ ⁻ ⁵⁾ = 5⁻² ;
__________________________________________
Note: (5⁻⁹ * 5⁻² ÷ 5⁻¹³) = (5⁻⁹ * 5⁻²) ÷ 5⁻¹³ ;
→ (5⁻⁹ * 5⁻²) = 5⁽⁻⁹⁾ ⁺ ⁽⁻²⁾ = 5 ⁽⁻⁹ ⁻ ²⁾ = 5 ⁻¹¹ ;
→5 ⁻¹¹ ÷ 5⁻¹³ = 5 ⁽⁻¹¹⁾ ⁺ ⁽⁻¹³⁾ = 5⁽⁻¹¹ ⁻ ¹³⁾ = 5⁽⁻²⁴⁾
______________________________________________
→ [ 5⁽⁻²⁴⁾ ] ² = 5⁽⁻²⁴ * ²⁾ = 5⁽⁻⁴⁸⁾ ;
_______________________________________________
Now, rewrite the entire problem; and solve:
→ 5⁽⁻⁴⁸⁾ * 5⁻² = 5⁽⁻⁴⁸⁾ ⁺ ⁽⁻²⁾ = 5⁽⁻⁴⁸⁻²⁾ ;
= 5⁻ ⁵⁰ .
