Simplify. 3 – 15 • 5 (1 point) • 0 • 78 • –72
Ya sure??
yes. you multiply first...
72 this is correct not negative
〖(-3)〗^3/〖(-3)〗^2 (1 point) –3 729 9
Follow PEMDAS. Multiply first. Then subtract. 3 - 15 * 5 3 - 75 -72
(-3)^3/(-3)^2 -3 729 9 that the qwestion?
Its -72. I used a calculator :) TRUST!!!
Please learn these rules carefully :) There are so many of these kinds of posts on Facebook and people just use the operations from left to right! Prove them wrong!! lol.
WTF there is no 72 theres 729?
Yes Johnnie. The last answer is -72. Thats the answer haha.
Please Excuse My Dear Aunt Sally: Parenthesis.Exponents. Multiplication. Division. Addition. Subtraction.
Yea pemdas. Idk where your gettin 729???
\[\frac{ -3^3 }{ -3^2 }\] Quotient of Powers: To divide powers with like bases, subtract the exponents. So you'd have: \[-3^1 or -3\]
He posted a second question on here.
The first question is -72. The seond one is -3.
But remember that multiplication and division BOTH have the same priority. And addition/subtraction also have the SAME priority. So what if you encounter an expression with both multiplication and division for example? In that case, you would go from left to right.
(Some people think because it's PEMDAS that you have to exactly follow that order). But bear in mind that there are some mnemonics out there that invert the MD and AS
