Question 88121
Multiply the number of people times the number of liters of water per person:
{{{6 * 10^9 *8.79 * 10^5 }}}
{{{(6 *8.79) * 10^9 * 10^5 }}}  When you multiply numbers like {{{10^9*10^5}}}, you add exponents!
{{{(52.74)*10^14}}}


Now, change to scientific notation by converting 52.74 to {{{5.274*10^1}}}.
{{{(5.274 *10^1) *10^14}}}
{{{5.274*10^15 }}}
