I need help with these pratice problems i have.

1. ^32x^3y^8

2. This one needs divided and simplify ^9 x^4 y^5/ 18xy^3

3. ^3 x^3 + ^4 x^6 -6^75 x^3

4. And if a triangle has sides of A=5 and C = 10 would the miss value of the other which is B would it be just 75 or 5to the power of 3 because I got 75 but when I reduce it i got 5 to the power of 3 i dont know if it means different when it aks the value?

^ means sqrt to the root and the other ^ means power to that number i hope someone could help

what does ^ mean?
I'll assume it means "to the power to"
Alright I think I know what you are talking about now. a better way to break these things up would be to put . in between terms like instead of ^32x^3y^8 you should make squareroot # or something and let ppl know and then make it #32.x^3.y^8. just trying to help.

1. #32x^3y^8
4#2.x^3.y^8, taking the 4 from inside the squareroot sign.
like this, #32 = #16.#2
and #16 = 4 so #16.#2 = 4#2

2. (#9.x^4.y^5) / (18.x.y^3)
becomes ( 3.x^4.y^5 ) / ( 18.x.y^3 )
which is then simplified to ( x^3.y^2 ) / 6

3. #3.x^3 + #4.x^6 -6.#75.x^3
#3x^3 doesnt change and #4.x^6 = 2x^6
and 6.#75.x^3 = 30.#3.x^3 because 6.#75 = 6.#3.#25 and #25 = 5 so 6.#3.5 = 30.#3
so the answer would be #3x^3+ 2.x^6 - 30.#3.x^3
this can be simplified to 31.#3x^3 + 2.x^6

4. if a triangle has sides of A=5 and C=10 then if it is a right-angle triangle, which i assume it is, the side B would be found using pythagores formula. A^2 + B^2 = C^2
so B^2 = C^2 - A^2
B^2 = 10^2 - 5^2
B^2 = 100 - 25
B^2 = 75
B = 5.#3

1. ^32x^3y^8 This cannot be simplified

2. This one needs divided and simplify ^9 x^4 y^5/ 18xy^3
= (x^3y^2)/2

3. ^3 x^3 + ^4 x^6 -6^75 x^3
This is not understandable

4. And if a triangle has sides of A=5 and C = 10 would the miss value of the other which is B would it be just 75 or 5to the power of 3 because I got 75 but when I reduce it i got 5 to the power of 3 i dont know if it means different when it aks the value?

If this is a right triangle then B^2=C^2-A^2
then B^2 = 10^2 - 5^2 = 75
B = sqrt(75) = sqrt (25)*sqrt(3) = 5*Sqrt(3)

-7= 3x-8 whilst putting -8 to the different ingredient of equation, the sign will exchange, so it is -7+8= 3x meaning a million=3x subsequently x= a million/3 and don't situation relating to the order, it is not proper! there's a rule in math relating to the order! you may genuinely verify it by utilising substituting a million/3 into the equation i.e -7= 3*a million/3-8 -7=-7!!!

I don't understand your notation
what is ^32 mean and same is true of ^3 and ^4?
