Collection Of Records For Crossword Clue Answers Units: When applying an exponent to a value with labeled units, be certain to likewise apply the exponent come the units: To apply an exponent come a base worth which is negative, the base value should be attached in a set of parentheses: (-4)2 = (-4) • (-4) = 16. The exponent then applies to the entire collection of parentheses come which that is attached. But, if the base worth is not enclosed in parentheses, the exponent applies only to the number to which the is attached. It does not use to the an unfavorable sign: -42 = -(4) • (4) = -16. Think that the an adverse sign as a multiple of (-1): -42 = (-1) • (42 ) = (-1) • (4) • (4) = -16. Or as the "opposite" that 42. (-4)2 is "negative 4 amount squared". -42 is "negative that 4 squared" or "opposite that 42 ".

Exponent the 1: A value elevated to one exponent the "one" is equal to itself. The exponent that one says the number of times the base is multiplied by itself. Since the basic is the only variable (occurs once) in the multiplication, it equals itself.
