=============================
Notation????
what you wrote was
(-6.8)(2)
which is 13.6 , d.
if you meant to type
(-6.8)^2
that is (-6.8)(-6.8) = 46.24
look, -14 * -14 works
but so does +14 * +14
by convention though the positive square root is used
so
10/7
5. Yes !!!
6. yes !!!
7. yes
8. result is POSITIVE so d is wrong
a and b are right
a. –13.6
b. 46.24***
c. –46.24
d. 13.6
