 Exponents: straightforward Information altoalsimce.org Topical summary | Algebra 1 summary | MathBits" Teacher resources Terms of Use call Person: Donna Roberts one exponent of a base value suggests the number of times the base worth is to it is in multiplied time itself.

You are watching: What is the number expressed using exponents  ; x is the basic value and also n is the exponent.
 Exponents represent mathematical shorthand for multiplication. number expressed utilizing exponents are called "powers". Larger calculators and also computers regularly use the operator ^ to represent an exponent. Naming: 24 is read "two elevated to the 4th power" or simply "two come the 4th". Exponents that 2 and also 3 have details designations: 22 is read "two squared" and 23 is check out "two cubed".See more: What Is The Mass Number Of Potassium 39 Have? Difference Between Potassium Units: When applying an exponent come a value v labeled units, be sure to likewise apply the exponent to the units: To apply an exponent come a base value which is negative, the basic value have to be enclosed in a set of parentheses: (-4)2 = (-4) • (-4) = 16. The exponent then applies to the entire set of parentheses to which it is attached. But, if the base worth is no enclosed in parentheses, the exponent applies only come the number to which it is attached. That does not apply to the an adverse sign: -42 = -(4) • (4) = -16. Think of the negative sign as a lot of of (-1): -42 = (-1) • (42 ) = (-1) • (4) • (4) = -16. Or together the "opposite" the 42. (-4)2 is "negative 4 quantity squared". -42 is "negative that 4 squared" or "opposite of 42 ".

Exponent that 1: A value raised to an exponent of "one" is equal to itself. The exponent the one states the number of times the base is multiply by itself. Due to the fact that the basic is the only aspect (occurs once) in the multiplication, it equates to itself.

 51 = 5 (-3)1 = -3 (ab)1 = ab (x + 4)1 = x + 4
