What is the length and width of 90 square meters?
If you mean a rectangle: choose any positive number for the first measurement. Then divide 90 by this number to get the second measurement.
What is the rules of PEMDAS?
The rules of PEMDAS are 1. Parenthesis anything in them you do first. 2. Exponents those little numbers next to the number telling you to multiply the number by itself a certain number of times 3. Multiplication and Division whichever comes first and 4. Addition and Subtraction whichever comes first. If there is an exponent next to parenthesis but there is no number that means the answer to the parenthesis has to be the thing that the exponent is next to. All of the rules apply inside of the parenthesis as well. If there is a number next to the parenthesis not followed by a symbol multiply the answer to the parenthesis by that number.
What is 4 to the 2nd power?
-2
What is the sum of the first eleven positive odd integers?
The sum of the first eleven positive odd integers is 121.
What are the 6 rules of exponents?
ExponentsExponents are used in many algebra problems, so it's important that you understand the rules for working with exponents. Let's go over each rule in detail, and see some examples. Rules of 1 There are two simple "rules of 1" to remember. First, any number raised to the power of "one" equals itself. This makes sense, because the power shows how many times the base is multiplied by itself. If it's only multiplied one time, then it's logical that it equals itself. Secondly, one raised to any power is one. This, too, is logical, because one times one times one, as many times as you multiply it, is always equal to one. Product Rule The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! Power RuleThe "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. Quotient Rule The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents. You can see why this works if you study the example shown. Zero Rule According to the "zero rule," any nonzero number raised to the power of zero equals 1. Negative Exponents The last rule in this lesson tells us that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.This information comes from http://www.math.com/school/subject2/lessons/S2U2L2DP.html
Why is a number to the first power equal that number?
For positive integer exponents, the exponent tells you how many times to take the base (the number being raised) as a factor then multiply. So x^3 = x * x * x (3 times). x^2 = x * x (2 times). x^1 = x (1 time). For negative exponents, do the same thing, but then take the reciprocal (1 divided by the number) to get the answer. Exponent of zero is defined to equal 1, for any nonzero base number. Rational exponents equate to taking a root (square root for 1/2, cube root for 1/3, etc). Irrational exponents cannot use these methods, but require using logarithms to solve.
What number is the first positive non-fibbonacci number?
4
How do you raise a exponent?
In the simplest case - a positive integer exponent - the exponent is an indicator of how often a number should be used as a factor. For example, 25 means that the number 2 should appear five times as a factor: 2 x 2 x 2 x 2 x 2. Exponentiation is also defined for an exponent of zero, negative exponents, and fractional exponents, but be sure to understand this simplest case first.
What is the definitions for exponents?
In the number x, with positive integer exponent a, a is the number of times that 1 (not the number itself) is multiplied by x. So, for example in the expression, 43 the exponent is 3 and the number represented is "1 is multiplied by 4 three times". If you multiply 4 by itself 3 times, you will get 4*4 (one time) * 4 (two times) *4 (three times) and that is NOT 43: it is just a wrong description.The laws of exponents are:xa * xb = xa+bxa / xb = xa-b(xa)b = xa*b(xy)a = xa * yaThe first three are used to extend the domain of exponents to negative integers and rational numbers. Exponents to irrational numbers are defined as limits of the exponents of the rational sequences converging to the irrational number.Finally, 00 is not defined (because it does not converge).
A positive number minus a positive number is always positive?
no not always. as long as the first number is bigger than the second number. if it is not, the answer is negative. 7-5=2 5-7= -2
Is a negative subtracted from a positive will it be a positive answer?
Yes. to subtract a negative is to add that number, so the number will be higher than the first number which is positive and can't go below zero.
Who were the first exponents of surfing?
none
What is a positive number minus a negative number?
a negative number minus a negative number is a negative number plus a negative number the answer depends on the value of the first number if the first number's absolute value is larger than the second number's absolute value than the answer is negative if the first number's absolute value is less than the second number's absolute value than the answer is positive
What is the first positive non Fibonacci number?
Since zero is both a positive number (defined as such), and not part of the Fibonacci sequence, then the first positive non-Fibonacci number is zero (0). If zero does not fit in you definition of positive number, then the answer would be four (4).
What does parenthesis around a number mean if it is raised to a power?
it means that you have to solve the exponents first and then do the rest. it follows a rule called PEMDAS:ParenthesisExponentMultiplicationDivisionAdditionSubtraction
What kind of number is 1 considered in mathematics?
1 is the first positive number on the number line.
When a number is being added to a positive number does the first number become smaller or larger?
Larger.
