Does 2 to the negative power of 2 equal negative 4?
No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
If The product of x and negative 4 is 8 more than 2 added to negative 5 times that number what equation could be used to solve for x?
x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5
What is a positive integer times a negative integer?
negative read this : "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)"
What does the plus sign over the minus sign mean?
Sometimes shown as ' +/- ' This means that the answer can be either positive(+) or negative(-). An example is 'square rooting'. The sqrt of '(+)4' is +/- 2 Because +2 X +2 =(+) 4 -2 X -2 = (+)4 With the square root of negative numbers , you are moving into the realms of IMAGINARY numbers, algebraically indicated by a lower letter 'i'. e.g. sqrt(-4) Becomes sqrt(-1)X sqrt(4) 'i' X sqrt(4) = i X +/-2 = either '2i' or '-2i'.
What integer divided by the sum of negative 4 and positive 6 equals negative 15?
Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.
What is negative divided a positive?
Here is a table for multiplication / division of positive/negative numbers. X/ + = + X/ - = - X/ + = - X/ - = + NB 'X/' means multiply or division. NNB If there is no sign in front of a number treat it as positive (+). e.g. 2 X 2 = 4 (Note ; no symbols, so it is treated as plus(+)) 2 X -2 = -4 -2 X 2 = -4 -2 x -2 = (+)4
What is x plus 4 negative 2?
It is x+2
What is the product of positive integer and negative integer?
A negative. Here is a little table, on multiplicatio/ division of positive and negative integers. = + = - = - = + NB If no sign is given , then read it as positive (+). e.g. 2 x 2 = (+)4 (No signs so read as (+)). 2 X - 2 = -4 -2 X (+)2 = -4 -2 X -2 = (+)4 .
What are the rules for multiplying or dividing negative and positive numbers?
Positive x Positive = Positive: 3 x 2 = 6Negative x Negative = Positive: (-2) x (-8) = 16Negative x Positive = Negative: (-3) x 4 = -12Positive x Negative = Negative: 3 x (-4) = -12
What does a negative number times a negative number equals?
negative multiply by negative is positive. While negative added with negative is negative. E.g. - 2 x -2 is 4 while -2 + -2 is -4
What is negative 2 to the power of 2?
-2 x -2 = 4
Why a negative number times a positive number will give a negative number?
Becuase in the rule of laws of signs, when you multiply or divide a number that is positve by a negative number or a number that is negative by a positive number (same thing), the product/answer will always be a negative number. But when you multiply/divide a positive number by positive or negative by negative, the product/answer will always be positive number E.g: -2 x 2= -4 / 2 x (-2)= -4 -2 -:- 2= -1 / 2 -:- (-2)= -1 E.g: 2 x 2=4 / -2 x (-2)=4 2 -:- 2= 1 / -2 -:- (-2)=1
Square root of x equals negative 2?
x = 4
What does X equal if X divided by negative 4 equals 2?

What mutiplies to 4 yet adds to negative 4?
8
How do you factor out x2 4?
x2 - 4 = (x + 2)(x - 2) x2 + 4 = (x + 2i)(x - 2i) where i is the square root of negative one.
