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.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
