How do I evaluate the expression [math]6 (x - 2) \cdot x[/math] for [math]x = 3?[/math]
Parentheses go first: 3-2 =1next comes multiplication from left to right, so6*1 = 66*3 = 18If your confusion is about the x, x is a variable, letter that can represent any number. x could be 5, 29, -3, 83284, 5.379549, or Pi, and without the "for x=3" part of the problem we do not know what it is. But in the problem they are telling you what value they want x to be. So, you replace x with 3 and solve the expression. If your confusion is about order of operations, see this site:Order of Operations - PEMDASI hope this helps!
Math question! : Evaluate these expressions without using a calculator vvvv?
8 = 2*2*2 = 2^3 8^11 = (2*2*2) x (2*2*2) x (2*2*2)...........upto 11 brackets which means a total of 2^11*3 = 33 twos that is 2^33 Now you have 2^33/2^28 = 2^5 = 32 2) 9= 3*3 And 27= 3*3*3 so 9^13 Means 3^13*2 = 3^26 and 27^8 = 3^8*3 = 3^24 so you have 3^26/3^24 = 3^2= 9
Math question-Evaluate expression?
1) log3 V27 = = log3 (27)^1/2 = = 1/2log3 27 = = 1/2log3 (3)^3 = = 3/2log3 3 = = 3/2 * 1 = 3/2 = 1.5. >>>> Answer 2) log4 192 - log4 3 = = log4 192/3 = = log4 64 = = log4 4^3 = = 3log4 4 = = 3*1 = 3. >>>> Answer.
Algebra: How do you evaluate an expression?
What kind of expression you are going to evaluate?As Stev Iones said, using calculators will tackle most of the problems, but I don't want to answer you too generally.But, since you asked the question too generally, I cannot answer you right now. How about you edit the question and ask me again afterwards? Thank you.
Math Problem: Evaluate the expression under the given conditions.?
Evaluate the expression under the given conditions. cos(θ − phi); cos θ = 5/13, θ in Quadrant IV, tan phi = −square root of 3, phi in Quadrant II I am completely lost and would love for a very detailed explanation. Thank you!
