Find the value of : (-7)^{2 × 7 - 6 - 8}

Solution:

Given, (-7)^{2 × 7 - 6 - 8}.

We have to find the value of the given expression.

By BODMAS rule,

2 × 7 - 6 - 8 = (2 × 7) - (6 + 8)

= (14) - (14)

= 0

So, (-7)^{2 × 7 - 6 - 8} = (-7)⁰

We know, a⁰ = 1

(-7)⁰ = 1

Therefore, the required value is 1.
