Solution:

[tex]LHS \\ = 8 + 7 - {2}^{2} \\ = 8 + 7 - 4 \\ = 15 - 4 \\ = 11[/tex]

[tex]RHS \\ = {3}^{2} + 2 \\ = 9 + 2 \\ 11[/tex]

So, LHS = RHS

Answer:

Below!

Step-by-step explanation:

Let's try the 'equal' sign for this equation.

  • 8 + 7 - 2² = 3² + 2

Remember, when it comes to simplifying, exponents come first. This means that we need to simplify the exponents first.

  • => 8 + 7 - (2 x 2) = 9 + 2
  • => 15 - 4 = 9 + 2
  • => 11 = 11

Since the LHS and the RHS are equal, the 'equal' sign will fit into the equation. Hence, this is proven as true. Let's try the 'not equal' sign.

  • => 8 + 7 - 2² ≠ 3² + 2
  • => 15 - 4 ≠ 9 + 2
  • => 11 ≠ 11

Now, this is a definite false. The 'not equal' sign is used when two values are not equal to each other, however, in this situation, 11 does equal 11. In between them is a 'not equal' sign. Hence, this is proven false.

We can conclude that the sign you are looking for is an 'equal' sign.

Hoped this helped.
