Answer:

2 4/7

Step-by-step explanation:

3/7+4/7= 7/7 or 1 whole

So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8

Hope this helped!!!

Answer:

2 4/7

Step-by-step explanation:

let n = number to add to 5 3/7

change 5 3/7 to improper fraction: 38

change 8 to become 56

create equation:

38 + n = 56

7 7

n = 56 - 38

7 7

n = 18 or 2 4/7

check: 5 3 + 2 4 = 8

7 7

5 + 2 = 7 and 3/7 + 4/7 = 1

7 + 1 = 8

Answer:

Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$

Step-by-step explanation:

We need to express the radical $\pm\sqrt{-81}$ using the imaginary unit i

Prime factors of 81 are: 3x3x3x3

and $\sqrt{-1}=i$

Solving:

$\pm\sqrt{-81}\\=\pm\sqrt{81}\sqrt{-1}\\=\pm\sqrt{3\times3\times3\times3}i\\ =\pm\sqrt{3^2\times3^2}i\\=\pm3\times3\ i\\=\pm9 \ i$

So, Solving the radical $\pm\sqrt{-81}$ we get $\mathbf{\pm9 \ i}$
