Help me please to simplify 8 to 8th power x 8 negative 8th power

Answer 1

first recall law of exponents,, if terms have the same base (or the number which is raised to a certain exponent), we can add the exponents,, thus:
8^(8) * 8^(-8)
we can rewrite this as:
8^(8-8)
8^(0)
since any number (expect zero) raised to zero is one,
8^(0) = 1

hope this helps~ :)
