What do they mean by a to the b power times a to the c power equals a b c power?
ab*ac=ab+c consider the powers of 2. 22=4, 23=8, 22*23=32=23+2=25 when multiplying a number by itself, you raise its power by one. when multiplying a number by itself n times, you raise it to the power of n, so if you raise a number to the power n, then the seame number to the power m, then multiply these together you are multiplying n+m times
Is negative 9 a natural number?
No, Negative Nine or -9 is not a natural number since natural numbers mean only those numbers which start from 1 to infinity. No negative integers are included in this category of numerals.
What is Negative three times a number increased by seven is less than negative eleven?
Let the number be x and if you mean: -3x+7 = -11 then the value of x is 6
Does a negative and a negative equal a positive?
If you multiply a positive number by a negative it always equals a negative number.Depends what you mean by "and".If they're added: neverIf they're subtracted: sometimesIf they're multiplied or divided: always
Why does 2 to the negative 2 power equal 0.25?
A negative power simply means the base should be inverted. What does this mean? Well in simpler terms: the base is on the wrong side of the fraction line. So x^(-y) (that is: x to the power of negative y) is the same as 1/x^y (that is: one over x to the power of y) So 2^(-2) (two to the power of negative 2) is the same as 1/2^2 (that is: one over two to the power of negative 2) 2^2 = 4 , so 1/2^2 = 1/4 1/4 (one quarter) is 0.25. Why do negative exponents work this way? Well, think of it like this. When we multiply like bases: 5^7 x 5^2 we simply add the exponents: 5^7 x 5^2 = 5^9 similarly, if we divide like bases, we subtract the exponents: (5^7)/(5^2) = 5^5 but (5^7)/(5^2) is just another way of saying: (5^7) x (1/5^2) so we can just rewrite it: (5^7) x (5^-2) and then we add the exponents (5 + (-2)) and get 5^5 So negative exponents are a very simple way of showing information without writing a fraction.
What does it mean to have the negative powers of ten?
Negative power of10 is a number which is 10% of its previous number. Like 10 power -1 = 0.1 10 power -2 = 10% of 0.1=0.01 10 power -3 = 10% of 0.01=0.001
What number is greater 10 to the power 390?
If you mean "greater than", you can raise it to a higher power.
What do they mean by a to the b power times a to the c power equals a b c power?

Is five negavite two is a positive or negative number?
I am going to say positive. If it is 5 -2 well that is 3, which is positive. Possibly you mean 5 with a small -2 slightly raised after it. That means 5 raised to the power of -2. Any time you have a negative exponent, you can take the reciprocal, and make it positve. So 5^-2 {the ^ symbol means to raise the power of} can be rewritten as 1/(5^2), which is 1/25. And this is a positive number as well.
Can power be a negative number?
Yes. -2^3, for example, is -8. This question is ambiguous - the questioner may mean "can the exponent be negative". In which case 2-3 is 1/8 or 0.125.
When a number in a fraction is negative does that mean that the whole fraction is negative?
Yes, it does.
What are negative intergery exponents?
I assume you mean "negative integer exponents".It means that: * It is an exponent * It is an integer (whole number) * It is negative (less than zero, i.e., with a minus sign) A negative exponent is defined as the reciprocal of the positive exponent. For example, 10 to the power -5 is the same as 1 / (10 to the power 5).
What is 5 to the power of negative?
If you mean 5 to the power of -1 then it is 1/5
What does the - sign mean before a number?
It means that the number is negative. Negative numbers are always under 0.
Can the sample mean be a negative number?
Yes, it can.
What is the physical significance of negative power in db?
dB expresses the ratio of two powers.Negative dB doesn't mean negative power.It means a negative ratio . . . less power compared to more power,or the power decreased.
Is the opposite of a negative number always sometimes or never a negative number?
never a negative number * * * * * ... true if, by opposite, you mean the additive inverse. However, the multplicative inverse is also an opposite. And the multiplicative inverse of a negative number is always negative.
