I am confused with the concept of mathematical expressions. How can I tell when a collection of operations and numbers is an expression?
Is "234x + - ÷ 14 - 23 46 -" an expression? Can you help me understand this concept?
Below are examples expressions for a variable. I need to explain my problem and answer just like the examples below, please give me a few problems to explain just like the samples below thanks...
A mathematical expression is similar to a phrase or fragment of a sentence. An expression has no subject and no verb or relatio
1.) compute thederivative of f(x)= arctan (x^2)
2.) compute thederivative of f(x)= ln(x^2/(2+x))
3.) determine an equation for the line tangent to the graph of y= xe^x at the point on the graph were x=2
Please refer to attached file for complete description of problems. Short description of problems is given below
1) Converting Exponents into radicals and vice versa.
2) Simplification of radicals in fraction forms
3) Converting the expressions into exponents with no negative exponents
4) Factorize the expressions
A parent is deciding which babysitter to use in the neighborhood. Babysitter A charges $20 per hour and a base rate of $60 per day. Babysitter B charges a base rate of $50 per day and $25 per hour. For how many hours of babysitting do the two babysitters charge the same amount?
