Question

(-2)^4+3 square root 120-20/4^3+|5(-1)|

Answer 1

Is this correct?\[(-2)^4+3 \sqrt{120}-20/4^3+|5×(-1)|\]

Answer 2

Yes

Answer 3

Okay, are you familiar with PEMDAS?

Answer 4

No

Answer 5

PEMDAS is an acronym for the order of operations. That is the order we are supposed to work math problems such as this.
P=Parenthesis
E=Exponential
M & D = Multiplication & Division
A & S = Addition & Subtraction
the M&D + A&S are to be done in order from left to right, whichever comes first.

Answer 6

Okay

Answer 7

First step is do all parenthesis:
\[(-2)^4+3 \sqrt{120}-20/4^3+abs(5×(-1))\]\[16+3 \sqrt{120}-20/4^3+5\]

Answer 8

Next Exponentials:
\[16+3 \sqrt{120}-20/64+5\]

Answer 9

Where did 64 come from?

Answer 10

the 4^3

Answer 11

Ok

Answer 12

Alright then just multiple and divide from left to right. I'm also going to simplify the radical but instead of dividing 20/64 I'm just going to simplify to avoid decimals.
\[16+6 \sqrt{30}-5/16+5\]

Answer 13

Final step is to add and subtract.
\[6\sqrt{30}+331/16\]

Answer 14

decimal form answer: 53.55085
