please help me simplify this expression!!
-12 divided by 3 x (-8 + (-4)^2 - 6) + 2
3 answers
and (10-6)^2+6x2-(3+2)^2
For the first one:
-12 / ( 3 x (-8 + (-4)^2 - 6) + 2 )
start with the most inside parentheses
(-8 + (-4)^2 - 6)
pemdas says exponents next
-8 + 16 - 6
=2
-12 / ( 3 x (2) + 2 )
inside parentheses
( 3 x 2 + 2 )
start with multiplication then addition
6 + 2 =
8
so it's
-12 / (8) =
-3/2
-12 / ( 3 x (-8 + (-4)^2 - 6) + 2 )
start with the most inside parentheses
(-8 + (-4)^2 - 6)
pemdas says exponents next
-8 + 16 - 6
=2
-12 / ( 3 x (2) + 2 )
inside parentheses
( 3 x 2 + 2 )
start with multiplication then addition
6 + 2 =
8
so it's
-12 / (8) =
-3/2
For the first one,
-12 / 3 * (-8 + (-4)^2 - 6) + 2
= -12 / 3 * (-8 + 16 - 6) + 2
= -12 / 3 * 2 + 2
= -4 * 2 + 2
= -8 + 2
= -6
You get -3/2 if you interpret it as bb did, but those extra parentheses are not there.
