Solve this for me √(1989 / 1989 * 1 + 1 * 1) ​

Question

Solve this for me

`√(1989 / 1989 * 1 + 1 * 1)`
​

Answer 1

`\large\tt√(2)`

`\begin{gathered} \: \end{gathered}`

Step-by-step explanation:

`\large\tt√( 1989 / 1989 * 1+1 * 1 )`

• Divide 1989 by 1989 to get 1

`\large\tt√(1* 1+1* 1)`

• Multiply 1 and 1 to get 1. Multiply 1 and 1 to get 1.

`\large\tt√(1+1)`

• And add 1 and 1 to get 2.

`\large\tt√(2)`

`\begin{gathered} \: \end{gathered}`

Answer 2

`\rm \color{teal} = √(2) \\ \\ \color{teal} \tt \: in \: \: alternate \: \: form \\ \\ \rm\color{teal} \: = 1.41421`

Step-by-step explanation:

`\bold \color{navy} √(1989 / 1389 * 1 + 1 * 1)`

• any expression multiplied by 1 remains the same

`\rm \color{red} √(1 + 1)`

• add numbers

`\bold \color{teal} √(2)`

`\rm \color{red} in \: \: alternate \: \: form \\ \\ \tt \color{pink} = 1.41421`

hope it helps
