Question

could someone help me with this problem (-12)2

Answer 1

is it \[(-12)^2\]

Answer 2

or (-12)*2

Answer 3

yes it's the first one

Answer 4

when the sign is inside the brackets you include it in the computation

(-12)^2 = (-12)*(-12)= 144

when it's outside like -(12)^2

then you only apply the negative sign at the end,

eg -(12)^2=-144

Answer 5

okay thanks for your help
