X^2-4x-5=0
according viet’s theorem
the roots are 5 and -1
If you want to know the concept of square roots and cube roots ?
the square root of a number is that number which when multiplied by itself two times gives us that number
e.g.
√64 = x , so that (x)(x) = 64
and from our multiplication table we know that
(8)(8) = 64 , so that
√64 = 8
the cube root of a number is that number which when multiplied by itself three times gives us that number
e.g.
∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64
so ∛64 = 4
By scientific notation I am assuming you mean standard form, as that is used primarily in scientific calculations. The answer in standard form would be
I hope this helps!
