Quick help with maths homework please? (Changed)

I think you guys are missing the point :P

 

 

 

 

 

 

 

He should learn how to do it without a calculator

 

 

 

 

 

 

 

The denominator of the fraction is the root you use (in this case, 2, so square root).

 

 

 

The numerator is the power of the term inside (in this case 3, so to the third power

 

 

 

Add that negative in front of the power in there and you divide one by the term :)

 

 

 

 

 

 

 

Sooooo

 

 

 

 

 

 

 

1/(sqrt(1^3))

 

 

 

 

 

 

 

EDIT: A different way to do this, shown to me by a friend:

 

 

 

 

 

 

 

1^(-3/2) == (1^(3/2))^-1 == 1/(1^(3/2)) == 1/(1^1 * 1^1/2) == 1/(1 * root(1,2))

Hmmm so

 

 

 

 

 

 

 

sqroot of 1/(1^3)

 

 

 

= sqroot of 1/1

 

 

 

= 1?

 

 

 

 

 

 

 

Maths is wierd :? .

 

 

 

 

 

 

 

I assume your math problem is something like this...

 

 

 

 

 

 

 

sqroot(1/(1^3))

 

 

 

Order of operations...

 

 

 

 

 

 

 

(Exponents) 1 times it self 3 times... 1x1x1=1

 

 

 

 

 

 

 

sqroot(1/1)

 

 

 

 

 

 

 

1 divided by one, you can only put one 1 in 1, so 1

 

 

 

sqroot(1)

 

 

 

what numbers times it self equals 1?

 

 

 

 

 

 

 

1.

 

 

 

 

 

 

 

the answer is one.

Totaly wrong.

 

 

 

 

 

 

 

1^-(2/3)

 

 

 

=1/1^(2/3)

 

 

 

 

 

 

 

=1

 

 

 

 

 

 

 

You NOWHERE take the square root of any number

I couldnt really tell from the topic post and by that post that he made, I thought the problem he's doing was like that.

 

 

 

 

 

 

 

*pulls out TI-84 plus Silver edition (calculator..)*

 

 

 

 

 

 

 

yup, 1.

 

 

 

 

 

 

 

If it were any number other than one... I wouldn't know how to do it with a fraction as an exponent.

 

 

 

 

 

 

 

EDIT: or 0.

1^(anything) is always 1. :D It is a special wonderful magical property of 1.

 

 

 

 

 

 

 

However, what if it were something else to the (-3/2) power? Let's just call it x^(-3/2). The - in the power means that you take the reciprocal of x^(3/2)... that is, the answer would be 1 / {x^(3/2)}. What does x^(3/2) mean? It means you take the square root (that is, the 1/2 power) of x^3.

 

 

 

 

 

 

 

That is, when a power is expressed as a fraction, the numerator is how many times you multiply x by itself, and then take the denominator'th root of what you get.

 

 

 

 

 

 

 

I hope that wasn't too confusing, and maybe even helped a little! :D

Everybody hug and spread the love :D
