Because both get cancelled out

Answer 2

Given : (-12)⁷ ÷  (-12)⁷

To Find : Value

Solution:

(-12)⁷ ÷  (-12)⁷

a ÷  a = 1  if  a≠ 0

any non zero  number divided by itself is 1

(-12)⁷ ÷  (-12)⁷  = 1

Law of exponents

$& {{\text{a}}^{n}}\times {{a}^{-n}}=1\text{ or }{{\text{a}}^{n}}=\frac{1}{{{a}^{n}}} \\ & {{a}^{m}}\times {{a}^{n}}={{a}^{m+n}} \\ & \frac{{{a}^{m}}}{{{a}^{n}}}={{a}^{m-n}} \\ & {{\left( {{a}^{m}} \right)}^{n}}={{\left( {{a}^{n}} \right)}^{m}}={{a}^{mn}} \\ & {{a}^{m}}\times {{b}^{m}}={{\left( ab \right)}^{m}} \\ & \frac{{{a}^{n}}}{{{b}^{n}}}={{\left( \frac{a}{b} \right)}^{n}} \\ & {{a}^{0}}=1$

(-12)⁷ ÷  (-12)⁷

= (-12)⁷⁻⁷

=  (-12)⁰

Any non non zero number raised to power 0 is 1

=> (-12)⁷ ÷  (-12)⁷  = 1
