Let z=6-7i and z^2=a+bi. what are the values of a and b ?

The values are

a = -13

b = -84

Step-by-step explanation:

Given:

z=6-7i and

To Find:

a = ?

b = ?

Solution:

Z is Complex Number consist of Real part and Imaginary part

We have

Using the identity we get

i² = -1

∴

Now on comparing with    equation we get

a = -13

b = -84

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong
