18
Write an expression of "2 raised to the 4th power" in exponent notation and solve
2^4, 16
Explain (in one sentence) why the square root of 2 is considered a real number but is not rational.
Because square root of 2 has a non-repeating, non-terminating decimal expansion, it is irrational but still lies on the real number line, so it is a real number.
Determine if the square root of 16 is is rational, Explain your reasoning.
It is rational, 4, 4/1
Riddle: I am an operation on exponents: when you multiply a^m×a^n I become a^m+n.
Name this rule and show a quick example using
a=2 , m=3 , n=2.
2^3 x 2^2 = 2^3+2 = 2^5 = 32
