(x^2+4)^1/2 - (x^2)(x^2+4)^-1/2 all over (1-x^2)^2/3? you are supposed to rewrite the expression as a single

...quotient in which only positive exponents and/or radicals appear-[√(x^2+4)- 1/√[(x^2)(x^2+4)]]/[(1-x^2)^2/3] X^1/2= √(X). X^-1/2= 1/X

Question about this math problem

I dont want the answer, I just want someone to explain to me how to solve this problem: 1. 5t-1=6t-5 I always get a problem like this wrong. My question is: do you subtract 5t from 6t or 6t from 5t

How can i solve these two expressions

not good in algebra alot :/ 1) -5(x+2y)+15(x+2y) x= 7 y= -7 2) 4(2m-n)-3(2m-n) m= -15 n= -18-1.)plug in the values for x and y -5(7 + 2(-7))+15(7 + 2(-7))-5(7 -14)+15(7 -14)-5(-7)+15(-7)35-105 35-

With Sin(20), draw a unit circle and determine it's value. How

Start with a simple cartesian grid. Draw a circle, and call this the unit circle. You know that in a unit circle, the radius is always 1. You also know that sin(A) = opp/hyp. hyp is thus always 1, an

Calculus: Can you help me find a limit

Alright, the problem reads like so: (x-1) / [√(x+3) - 2] And I have to find the limit as it approaches 1 mathematically.(This would be so much easier with a graph...) I multiplied by the conjugate,

How do you solve this integral? Integral of e^x/(e^x + 1) dx

In general, ∫ du/u = ln(u) + c ∫ e^x/(e^x + 1) = ln(e^x + 1) + c

What is 1/8+8/9 when you add two fractions

/ means separate from fraction numerator and denominator can you tell the least common denaminator and than tell how you solved it-1/8 + 8/9 9/72 + 64/72 73/72 1 1/72 Least common denominators can be

Derivative Q/Calculus

How do you solve (3^(3+h)-3^3)/(h)? The exact problem is to find the derivative of f(x)=3^x at f (x)=3.-Hello, The derivative of a power fonction is obtained by the use of the exponential expression

If g(x) = x + 1 over x - 1 , x cant = 1 find g(2x)

so all i have right now is g(2x) = 2x + 1 over 2x - 1 whats the next step? is that even right?-Dont forget x cant = 1/2!-Youre correct and done. g(2x) = (2x + 1)/(2x - 1)

Please explain the sum very clearly clearly

If b^2-4ac=0 then show ax^2 plus bx plus c is a perfect square-If b^2-4ac = 0 then b^2 = 4ac. We can then write ax^2 + bx + c as ax^2 +- 2 sqrt(ac) + c, which can also be written as ( sqrt(a)+-sqrt(b

Does a hyperbola have a major axis or axis of symmetry

Same as above.-The line that passes through the two vertices is called the semi-major axis.The entire shape actually has 2 axes of symmetry:one that is the same as the semi-major axis, and one that is
