Question

which expression is equivalent to (sqrt x-5)^7
a(x-5)^1/7
b(x-5)^7/1
c(x-5)^7/2
d(x-5)^2/7

Answer 1

\[(\sqrt{x-5})^7\]

Answer 2

\(\huge \sqrt{a}=a^\frac{1}{2}
\\\huge (\sqrt{x-5})^7=((x-5)^\frac{1}{2})^7\)

now recall that when you raise one power to another, you multiply the exponents. \(\huge (a^b)^c=a^{(b*c)}\)

Answer 3

so c

Answer 4

thats what i got and its right lol
thank you :)
