Question 112650
{{{2^-3}}}
What do I get if I multiply by {{{2^3}}}?
{{{(2^-3)(2^3) = 2^(-3 + 3)}}}
{{{(2^-3)(2^3) = 2^0}}}
{{{2^0 = 1}}}
Now what do I get if I multiply {{{1 / 2^3}}} by {{{2^3}}}?
{{{(1 / 2^3)*(2^3) = 1}}}
I can replace the 2 by any other number and the 3 by any other
number and this is still true.
{{{2^-3 = 1 / 2^3}}}
