Q1 Sarah thinks of a positive number. She calculates that the square of the number is 256.
What is the square root of the number?
(Also plz explain how u get the 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.

to rewrite a literal equation you may need to divide by a number, or by a variable.

hope i .

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
