The √-16 + √49 can be written in the complex form as a + ib is 7 + 4i where i is the iota.
What is a complex number?
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have:
= √-16 + √49
As we know √-1 = i (iota)
= (√-1)(√16) + √49
√-1 = i
√16 = 4
√49 = 7
= 4i + 7 or
= 7 + 4i
Thus, the √-16 + √49 can be written in the complex form as a + ib is 7 + 4i where i is the iota.
