Hey guys,
I've had a really tough day today, and am now struggling with the easiest of maths problems. I can see this happening a lot, so I have had the idea of giving a prize at Xmas to the person that I have judged to have helped me the most.
Here are the problems for today:
1.
express 1
---------
(root a)^4/3
in the form a^n
2.
by letting y=x^1/3 find the values of X for which x^1/3 - 2x^-1/3 = 1
3.
express in the form 2^n
a. 2^1/3 + 2^1/3 + 2^1/3 + 2^1/3
b. 2^100 - 2^99
c. 8^0.1 + 8^0.1 + 8^0.1 + 8^0.1 + 8^0.1 + 8^0.1 + 8^0.1 + 8^0.1
4.
solve the equation
125^3x = 25^x-2
------- --------
5^x+4 3125
5.
find the equation of the straight line that passes through the points (3,-1) and (-2,2). Find point of intersecton of x axis
Thanks guys
