Question:

3 squared to the 4th power

Answers

3 squared to the 4th power is 6561

1) 3^2=9

2) 9^4=81*81=6561

There are 2 x intercepts

Step-by-step explanation:

I just took the test and the answer is B

The  answer
the complement of the question is perhaps the function
f(x)= x4 - 5x2
to find the value of x-intercepts, just egalize f(x)= x4 - 5x2  to 0, and solve the equation.
that is x4 - 5x2 = 0 equivalent to  x²(x²-5) = 0, this implies x²-5 = 0 and  x²=0,
it implies x=0  and x²= 5, which means  x = +/- sqrt(5)

so the x intercepts are x=0, x = - sqrt(5) and x = +sqrt(5)

finally the answer is 3 x intercepts

According to the Fundamental Theorem of Algebra, we will find which polynomial function has exactly 8 roots

the number of roots is equal to the highest degree of the polynomial functions

among the 4 functions,
b.f(x)to the 5th power+3xto the 4th power+12xcubed+7xsquared -2x+15
 is unknown (something is lack at the first term)

the 3 others doesn't match to the question, so it depends on the " choice b"

by contrast, 
According to the Fundamental Theorem of Algebra, the polynomial function that has exactly 6 roots is 
d.f(x)7xto the 6th power+3xcubed+12 (the degree is 6)
