hey everyone i got a series of questions so can somebody check my working out and see if they are right thanks.(adsbygoogle = window.adsbygoogle || []).push({});

1. Make t the subject of the formula 1/g= 1/(t+1) - 1/(s-1)

i did all the working out and got at the end

t= GS-2G-S+1 / S-1+G not sure if i should make it simplier like

t= G(S-2) - S + 1 / G+s-1

2. solve the equation 6x^3 + 8 = 23x^2 + 6x

i can only get the intercepts using my calculator sketching both graphs and finding the intercepts how do you do it manually????? i tried bringing them all to the LHS and let it equal to zero and subing x to get 0 on the RHS but never happened is there a way i dont think so!!! if there is plz tell me

3. Write in simplest index form:

sqrt ( x^8 * y^4 * z^2) / x*y*z^2

i got totally confused do i just do [(x^8*y^4*z^2)^(1/2) ] / xyz^2

that gives me

= x^4*y^2*z / xyz^2 = x^3*Y*z^-1

therefore

= x^3*Y / Z IS THAT RIGHT PEOPLE???? PLZ HELP THANKS

THATS ALL PLZ HELP ME EVERY1 HEHE :P IT WILL BE MOST APPRECIATED
