729^(-(1/3)) ?

step-by-step, using rules/conventions of exponents:

(problem) 729^(-(1/3)) = 9^(-1)

9^(-1) = 1/9

1/9 = 1/(3^2)

1/(3^2) = 3^(-2) (answer)

Is there a way to find the least common denominator of a fraction(which happens to be just the LCM of a denominator)?

HOW CAN USE THE LCD/LCM

hello out there, maybe you have heard it said,that great minds can't do simple math. e.g. einstein. now to save myself the embarrassment of asking such a simple question, let me just say first; my knowledge of math is so vast that there are many gaps.

El precio de una taza de café era $2.35 el día de ayer. Hoy, el precio cayó a $2.20 . Hallar el porcentaje de disminución. Redondear la respuesta a la décima más cercana de un porcentaje.

this is not a stupid question at all believe me it confuses a lot of people the order in which simultaneous arithmetic occurs.. AS SOME OF THE ANSWERS HERE INDICATE.. the rule to this is nicknamed BODMAS meaning Brackets Contents First then Divisions, Multiplications Additions and Subtractions.. that is the order in which the maths will occur.. so back to your question:

6/2(1+2)

WE PERFORM THE CONTENTS OF THE BRACKETS FIRST (1+2) = 3

THEN DIVISIONS OCCUR NEXT

6/2 = 3

NEXT MULTIPLICATIONS OCCUR

3*3 = 9

SO THE FINAL ANSWER IS 9.

PS: I AM ASSUMING THE NO OPERATOR RULE THAT WHEN TWO NUMBERS EXISTS SIDE BY SIDE IN AN EQUATION THE OPERATOR IS MULTIPLICATION.

it is an annual rate so you need to find the effective monthly rate, divide the 9% by 12 months gives you .75%.

Multiply this by the $50,000 and you get $375

alternatively find the annul interest and divide by 12

that is 9% * 50,000 = $4,500

divide this by 12 months and you get $375

at best, you can factor to give

ab(12a+17b)

GuestDec 20, 2012

I believe you want to take 15% of 2888, 0.15 * 2888 = 433.2,
so 2888 - 433.2 = 2454.8

You can't divide by zero.

(3/0) = ∞
So, it shows error by that reason.

1. state problem

b + 8 = -9

2. subtract 8 from both sides

b + 8 - 8 = -9 - 8

3. simplify

b = -17

GuestDec 19, 2012

assuming that you posted the problem correctly,

2888 - 15% = 2888 - (15/100) = 2888 - 0.15 = 2887.85

(3/6)/(3/0) = (3/6)*(0/3) = (3*0)/(6*3) = 0/18 = 0

IdiotLOL:
WHAT IS 6/2(1+2)?? IS IT 1 OR 9?

Some of the answers here are pretty crazy. It's 9.

You do brackets first therefore 1+2=3,

6/2(3)

then you divide six by two = 3

3(3)

Finally, you do distributive property and multiply three by three.

9

There you go! You have your answer!

GuestDec 18, 2012

According to the web calculator, its 9.
Parentheses first, then the division from left to right (So do 6/2 first, or three) and three times three is nine.
