X to the 2nd power = -169 what is x

Mathematics
1 answer:
ikadub [295]3 years ago
7 0

Given:

x^2=-169

To solve for x, we need to cancel the exponent. To cancel a square, we need to square root both sides.

\sqrt{x^2}=\sqrt{-169}

The square root of 169 is 13, but since it is negative, we need to put the imaginary unit, i, in front of the answer. (i=\sqrt{-1})

Simplify.

x=13i

If you have not learned imaginary numbers or the imaginary unit yet, you could say that x=\sqrt{-169}.

Which equation is an identity? (Can someone explain to me how they got their answer, I don't get this.)
Greeley [361]
5w + 8 - w = 6w - 2(w -4).

Let's reduce the equation on the left:

4w + 8; (1)

and now let's reduce the equation on the right

6w - 2w +8 = 4w +8 (2).

We notice that (1) ≈ (2), and this is the only IDENTITY

(a^2-ax+bx-ab)/(a^2+ax-bx-ab)*(a^2+ax+ab+bx)/(a^2-ax-ab+bx)
Vanyuwa [196]
\frac{a^2-ax+bx-ab}{a^2+ax-bx-ab} \cdot \frac{a^2+ax+ab+bx}{a^2-ax-ab+bx} = \frac{1}{a(a+x)-b(x+a)} \cdot (a(a+x)+b(a+x)) = \frac{1}{a-b} \cdot (a+b) = \frac{a+b}{a-b}.
