it means that you have to solve the exponents first and then do the rest. it follows a rule called PEMDAS:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
(16 x 22)2 = (16 x 4)2 = (64)2 = 4096. Always perform the operations inside parenthesis first.
You square the number in the parentheses.
Any number raised to the power of 1 is equal to itself.
Any number raised to the power 0 equals 1.
When a negative number is raised to an even power the result is a positive number
It is: (0.5)-4 = 16
(-3)^2 =9 but -3^2 = -9
(16 x 22)2 = (16 x 4)2 = (64)2 = 4096. Always perform the operations inside parenthesis first.
The power could then be called an exponent. The number that is being raised to a power is called the base. In the case of 42, the exponent is 2 and the base is 4.
You square the number in the parentheses.
one over 3 a3
A number raised to the second power is a number times itself. This can also be stated as a number squared.
Any number raised to the power of 1 is equal to itself.
Any number raised to the power 0 equals 1.
When a negative number is raised to an even power the result is a positive number
A number raised to the power "a" is multiplied by itself "a" times. For example, 5 raised to the power 3 is 5x5x5=125. 2 raised to the power 5 is 2x2x2x2x2=32.
Any number raised to the power of 1 is the number itself. Example, 250 to the power of 1 is 250.
