# How to factor these equations? TRY IT. NOT AS EASY AS IT SOUNDS!
#### nigahiga
##### New member
1 + 3^(x/2) = 2^x
( √(2-√3) )^x + ( √(2+√3) )^x= 2^x
How do you factor that and find the answer? Seriously?

STATE THE LINEAR APPROXIMATION FOR: (2.04)raise to power 5
• FURTHER MATHS -
There are lots of possible approximations. If we have
y = x^5, the slope of the tangent line is
y' = 5x^4
At (2,32), the slope is 80
so, if a(x) is the line,
a(x) = 80(x-2)+32
a(2.04) = 80(.04)+32 = 35.2
