it was meant to be 3/2

x= -2

I guess i din't explain the game. You should show your working. And no next question?

`what is y raised to power -10

To answer nike's question.

25 to the power of 3/2

25=5 to the power of 2.

therefore: 5 ^2x3/2

5³ = 125

i dont get the last question?

next question: it took 10 people to lift 5 bags, how many people will it take to lift 10 bags?

20 people

double the 10..

5x2=10
10x2= 20

i cant explain much cos i just worked out in my head

my question was wats[b] y raised to the power of -10[/b]

20

I dont know the answer oo. Wes, can u please explain how Y^-10 is 20?

nike asked how many people it'll take to lift ten bags and i answered 20. i guess she modified her post

Lizzy how u get de raised to power sign

y raised to power -10

any thing dat has minus b4 de power will be reduced to

1/y raised to power 10..

i thought we had to solve for Y . . . . you should have said "what's another way to write the statement".

to get the raised to power sign... you higlight the thing you wanna raise.. and click SUP. It's right above the smileys.

thanks

y^-10 = 1/y^-10

Okay..

next question: Factorize.

x²+2x-3 = 0

hmmm, i like this game......

hot-angel:

Okay..

next question: Factorize.

x²+2x-3 = 0

where dis u press on the keyboard to make 2 the power of x, i can't.

x2 + 2x - 3 = 0

ans: x2 +3x - x - 3 = 0
x(x + 3) - 1 (x + 3)
(x + 3) = 0 (x - 1) = 0
x = -3 or x = 1

Queen for you to raise something to the power... you highlight what you want to raise, and click SUP, it's right above the smileys.

There's no next question??

NExt Question:

If f(x)= x-4; Find f(4), and f(-2).

ok hottie thanx

hot-angel:


NExt Question:

If f(x)= x-4; Find f(4), and f(-2).

f(4)  = 0
f(-2) = -6

Find the sum of the following GP (Geometric Progression)
2 + 6 + 18 + 54 + ... + 1458

umm. . wow. . . my ppl need more math. .

the lowest common multiple of 24 and 48 is rightly 48.
the highest common factor of 24 and 48 is 24 - 24 is a factor of itself.

factors of 24: 1,24, 2,12, 3,8,4,6
factors of 48, 1,48, 2,24, 3,16, 4,12, 6,8

you guys sure learned weird ways of doing stuff. . .

so its 24 and 48?

if it is..am right

yes - 24 is the lcf, 48 is the lcm.

then am right huh?

yep, you are right!

Now, my own question:

What is the probability of getting at least two heads when a fair coin is flipped three times?

answer is[b] 4/8[/b]

when you fliped coin 3times , total outcome is 8 because 2³ is 8 and probability of at least 2 heads is 4 therefore, its 4/8

u feel me?

solve (2 ^7/9) ^1/2?

Your answer is Correct!!!

though, its not that the probability of 2 head is 4, but the total number of possible ways of getting two heads is 4.

And the answer to your question,

(2^7/9)^1/2 = 2^7/18

so, answer this:

what is wrong with this proof:

x = y.
Then x² = xy.
Subtract the same thing from both sides:
x² - y² = xy - y².
Dividing by (x-y), obtain
x + y = y.
Since x = y, we see that
2 y = y.
Subtracting y from both sides:
y = 0

kamakula am sorry to bust your bubble but your answer is wrong!

(2 ^7/9) ^1/2= 5/3 or 1 ^2/3
how its done:
first change (2 ^7/9) into an improper fraction which is 25/9

then 1/2 means squareroot..u feel me?

therefore its gon be √- sqareroot of 25/9 which is 5/3:
25-5
9-3
so answer is 5/3 or 1 ^2/3

do u get it ?

kamakaula.. i don't get the LCM thingy.

And i seriously don't know how to do proofs. Call me dumb.

gurl ur not dumb ok..

do the long hcf and lcm thing we were taught in primary school, u'll get it
but if u know venn diagram, it works too

I used the way i knew.. but that's wat i keep getting.
