## anonymous one year ago Will Medal! Calculate | -3 + 4i |.

1. anonymous

-25 + 8i?

2. anonymous

no

3. anonymous

the absolute value of a complex number is a positive real number

4. anonymous

$|a+bi|=\sqrt{a^2+b^2}$ just like pythagoras ignore the $$i$$ entirely

5. anonymous

Oh ok! So $\sqrt{-3^{2}+ 4^{2}} = 5$

6. anonymous

no minus signs

7. anonymous

but yeah, $$5$$ is the answer

8. anonymous

Great! Thank you for you time and help!
