Quiz on rational exponents and radicals.

by Donnalyn Tañala

What is a rational exponent?

an exponent that is a fraction

an integer exponent

an exponential function

a negative exponent

Express b^(m/n) in radical form.

root of b with index n divided by m

n-th root of (b^m)

b^(1/mn)

m-th root of (b^n)

Which is the product rule for exponents?

a^m * a^n = a^(m+n)

a^m * a^n = a^(m-n)

(a^m)^n = a^(mn)

a^m / a^n = a^(m+n)

What is b^(-m/n) equal to?

b^(n/m)

1 / b^(m/n)

n-th root of b^m

b^(m+n)

How do you interpret b^(3/2)?

cbrt(b^3)

sqrt(b^3)

b^3/2

sqrt(3b)

Which equals cube root of (b^2)?

b^(2/3)

b^(1/3)

b^(3/2)

b^(2/1)

What is the zero exponent rule?

b^0 = 0

b^0 = 1 (b ≠ 0)

b^0 = b

0^b = 1

Power rule: (b^m)^n = ?

b^(m/n)

b^(m+n)

b^(n/m)

b^(m n)

Rational exponent form: b^(m/n) = (b^m)^(1/n) true or false?

true

I can't determine

false

Only when b>0

What does b^(1/n) represent?

the n-th root of 1/b

the reciprocal of b^n

the n-th root of b

the n-th power of b
