Answer:
The number is 0.
Step-by-step explanation:
The square root of a number less than 4 is 2.
[tex]\\ \sf{} \sqrt{4 - x} = 2[/tex]
Find the number.
[tex]\\ \sf{} \sqrt{4 - x} = 2[/tex]
Square both sides.
[tex]\\ \sf{}4 - x = 4[/tex]
[tex]\\ \sf{} - x = 4 - 4[/tex]
[tex]\\ \sf{} - x = 0[/tex]
[tex]\\ \huge \boxed{\sf{}x = 0} \\ \\ \\ [/tex]
Check to verify:
[tex]\\ \sf{} \sqrt{4 + 0} = 2\\ \\ \sf{} \sqrt{4} = 2 \\ \\ \sf{}2 = 2 \\ \\ \\ [/tex]
