What number equals nine squared?
To square a number means to multiply it by itself. Thus, 92 (read: nine squared, or nine to the second power) = 9 x 9=81
What is the Difference between a square and a square root?
A "square" (2nd power) is the result of multiplying a number by itself. For example, the square of 3 is 9 because 3 x 3 = 9. A "square root" (-2 power) is in the opposite exponential direction: you are finding the number which multiplied by itself will equal your given number. Using the same example, the square root of 9 is 3, because 3 x 3 = 9. Except for numbers that are squares of integers, most square roots will be long non-repeating decimals. (The square root of 2 is 1.414213562...)
What square number comes after 16?
25. Square numbers are numbers that result from integers being raised to the power of 2. 1^2 = 1. 1 is the first square number. 2^2 = 4. 4 is the second. 3^2 = 9. 4^2 =16. 5^2 = 25.
What is the symbol of squared?
squared is simply written as a constant raised to the second power. For example, 3 to the second power=9. The way to write the power, or exponent, is by writing a superscript (small number in the uppper righthand corner of the number or variable) number 2.
Which number has the square root of 9?
3 or -3. 32 = 9 and (-3)2 = 9 * * * * * +3 and -3 do not have the square root of 9 - they are the square roots of 9. The number 81 has the square root 9.
What is nine to the second power equal?
81 A number raised to the second power is the number multipled by itself twice (9*9). A number raised to the third power, is the number multipled by itself 3 times (9*9*9) and so on.
What number equals nine squared?
To square a number means to multiply it by itself. Thus, 92 (read: nine squared, or nine to the second power) = 9 x 9=81
How do you write the number 81 as a power?
9 to the second power :))
Difference between negative number to the second power and negative number in parentheses to the second power?
-3^2 = 9 -(3^2) = -9
Why does it make sense to call 25 a square number?
A square number is a number that can be simplified to another number raised to the second power. For example 25, is 5^2, 16 is 4^2, 9 is 3^2 and so on.
9 to the power of 0.5?
9 to the power of 0.5 is the square root of 9, which is equal to 3. This can be calculated by raising 9 to the power of 0.5, or by using the square root function on a calculator. In mathematical terms, 9^0.5 = √9 = 3.
What is nine to the second power?
9 to the 2 power is 81 9x9=81 When you are calculating powers you are really multiplying the first number by itself the number of times the second number says. so for 9 to the 2 power you are multiplying 9 by itself 2 times
What is the standard form for 9 to the power of 2?
Nine to the second power is just nine times nine. Any number with a power is just a number that can multiply itself. 2 9 =9*9=81
What makes a number a square number?
I don't know if this is what you mean, but to make a normal number a square number, you have to times it by itself*****I suspect though, that the answer is as follows:A square number is one that is the product of some integer multiplied by itself. This second integer is the square root of the original number. Thus, 9 is a square number since 3*3 = 9
What is the difference between a square root and a square number?
3 is the square root of 9. 9 is a square number. 9 is the square root of 81. 81 is a square number.
What does raising a number to the second power mean?
multiply the number by itselfRaising a number to the second power means you are squaring the number, multiplying it by itself. 2 squared= 2*2=43 squared=3*3=9
What is the square root of y to the second power over 81?
(y2/81)1/2 = y/9
