The difference is whether the exponent attaches to just the 2 or to the negative sign as well
-2^4 = - (2x2x2x2) = -16
(-2^4) = -2 x -2 x -2 x -2 = +16
$3000 from friend, $6000 from bank, and $1000 insurance
11 miles in 1/4 hour
1/4 of an hour is 15 minutes
so 11 in 15 minutes
x /60 = 11/15
cross multiply
x*15 = 60 * 11
15x = 660
divide both sides by 15
x = 44
the unit rate of the hikers in miles per hour is 44 mph.
You can also solve like this
1/4 of hour is 15 minutes
to get to the whole hour you would multiply by four
so you'd (11miles in 1/4 hour) * 4
44 miles in 1 hour
Hope this helps :)
