Any answers plz and thank u

Answer:
a²-6=b
Step-by-step explanation:
[tex]a=\sqrt{b+6}[/tex]
taking square on both sides
a²=(√b+6)²
square root will be cancelled by square
a²=b+6
a²-6=b
Answer:
[tex]b= a^{2} -6[/tex]
Step-by-step explanation:
[tex]a = \sqrt{b+6}[/tex]
→ First square both sides to get rid of the root
[tex]a^{2} =b+6[/tex]
→ Minus 6 from both sides to isolate b
[tex]a^{2} -6=b[/tex]
→ Or
[tex]b= a^{2} -6[/tex]
