Answer:

4

Step-by-step explanation:

The square root of the number is 4.

because she is thinking number 16.

She is thinking of √256;

then the square root of √256 is being asked.

√(√256) = √ 16 = 4

another way of answering the question:

let x be the number she is thinking

x² = 256

x =  √256

x = 16

then square root of 16 is 4.
