simplify each expression. Your answer should still be in exponential form and only have positive exponents.
x^-b
8 answers
is that x is greater than negative b or x is less than negative b
no its a exponent x with exponent -b
Is that what it look like on your homework x^-b?
yea
I'm kinda confused with this problem. Is it in Geometry, pre algebra algebra 1 or algebra 2 or so on?
secondary math 2
what grade, r u in connections
based on a fundamental rule of exponents
a^-b = 1/a^b and a related version (a/b)^-x
= (b/a)^(+x)
e.g. 2^-3 = 12^3 = 1/8
(2/3)^-2 = (3/2)^2 = 9/4
so for yours: x^-b = 1/x^b
a^-b = 1/a^b and a related version (a/b)^-x
= (b/a)^(+x)
e.g. 2^-3 = 12^3 = 1/8
(2/3)^-2 = (3/2)^2 = 9/4
so for yours: x^-b = 1/x^b
