What is the value of (9^7) ^3/14, in simplest terms? a0
s2008m [1.1K]

Answer:

27.

Step-by-step explanation:

It is one property of exponents that for any numbers <em>a, b,</em> and c

(a^b)^c=a^{bc}

Therefore, using this property the expression  (9^7) ^{3/14} becomes

(9^7) ^{3/14} =9^{(7*\frac{3}{14} )}.

and when when simplify the exponents, we get:

9^{(\frac{21}{14} )}= 9^{\frac{3}{2} }= (9^{\frac{1}{2} })^3.

Since for any number  a^\frac{1}{2} =\sqrt{a} <em>( </em>\dfrac{1}{2}<em> in the exponent means the square root) , </em>(9^{\frac{1}{2} })^3 is rewritten as

(\sqrt9} )^3

which simplifies to

(\sqrt9} )^3=3^3 =\bold{27}

Thus,

\boxed{ (9^7) ^{3/14}=27}
