Answer:
Step-by-step explanation:
I will assume that you want to write this number in scientific notation
(5 x 102)⁻²
So, first, we are going to solve the parenthesis and we get 5 x 102 = 510.
(5 x 102)⁻² = (510)⁻²
However, we know that when we have negative exponents we can make them positive by let them become part of the denominator, therefore we would have:
(510)⁻²=

↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
Therefore, the answer for Complex Number System is (5±√7i)/2
