Remember
∛(ab)=(∛a)(∛b)

also
i¹=i
i²=-1
i³=-i
i⁴=1

so

∛-2i=(∛2)(∛-i)=(∛2)(i)=i∛2

Answer:

i√(2i)

Step-by-step explanation:

Imaginary numbers are complex numbers which can be represented as real numbers by multiplying them with imaginary unit (i = √-1). -2i is an imaginary number. Heron of Alexandria is thought of to be the first person to have used imaginary numbers.

Cube root of -2i

√-2i

= i√2i

= -8×(√-1)³

= i√2i

= i√2i

√-2i

= i√2i  

∴ The expression is a CUBE ROOT of -2i is i√(2i)

harina [27]

Answer:

90 degrees

Step-by-step explanation:

A circle circumscribed over a right triangle is the same as a circle circumscribed over a rectangle built from the extension of the right triangle.

That tells us that the hypotenuse is the diameter of the circle in that case.

Here, we can see a triangle that has the hypotenuse as the diameter of the circumscribed circle. We can infer that the triangle is a right triangle.

1. what two things need to be true in order to add/subtract two radicals ?
Novay_Z [31]

Answer: 1. To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.2.The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical.3.When factoring a trinomial in the form x2 + bx + c, consider the following tips. Look at the c term first. o If the c term is a positive number, then the factors of c will both be positive or both be negative. In other words, r and s will have the same sign.
