What is a positive integer exponent?
An exponent that is a positive integer. For example, x3 has a positive exponent, while 8-5 does not.
Meanning of positive exponent?
An exponent is the power that a number is raised to. For instance, in the expression 3^2 ("three squared"), 2 is the "exponent" and 3 is the "base." A positive exponent just means that the power is a positive number. For instance, the following expression does not involve a positive exponent: 3^(-2). Horses rule!!!!!
When is the exponent positive?
When the number is very large 1.0 x 10^6 is 1 million.
Evaluate the powers of 10 and a exponent of positive 4?
You evaluate the powers of 10 and a exponent of positive 4.
What is a positive exponent?
An exponent that is a positive integer. For example, x3 has a positive exponent, while 8-5 does not.
How do you predict whether a power will be negative or positive?
To predict whether a power will be negative or positive, examine the base and the exponent. If the base is positive, any exponent—whether positive or negative—will yield a positive result. Conversely, if the base is negative, an even exponent results in a positive value, while an odd exponent produces a negative value. Thus, the sign of the power depends on both the sign of the base and whether the exponent is odd or even.
What is the difference of exponent and scientific notation?
scientific notation tells how many times you will move or add zero either left(positive) or right (negative). exponent tells you how many times you will multiply its coefficient.
When rewriting an exponential expression with a negative exponent and a positive base to an expression containing only a positive exponent does the sign of the base change?
No.
How do you raise anumber to a negative exponent?
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
Some of the numbers in scientific notation have a negative exponent and some have a positive exponent. Explain the difference between these tow types of numbers.?
The mantissa is multiplied by 10 raised to the power as shown by the exponent. So, if the exponent is 4, then you multiply the mantissa by 10^4 = 10,000. If the exponent is -4 then you multiply the mantissa by 10^(-4) = 0.0001 or, equivalently, divide by 10^4.
How can an expression with a negative exponent be changed into one with a positive exponent?
Say it with a lot of sarcasm.
How do you change a negative exponents to positive?
To change a negative exponent to a positive one, you take the reciprocal of the base raised to the positive exponent. For example, ( a^{-n} ) can be rewritten as ( \frac{1}{a^n} ), where ( a ) is the base and ( n ) is the positive exponent. This rule applies to any non-zero base.
