2^3 ( carot sign “^” means exponent!)
2 x 2 x 2=8
16^(1/2)
square root of 16 = 4
16^(-1/2)
1 / (square root of 16) = 1/4
MADSPM (for exponents with same base)
If multiplying the bases, add the exponents; if dividing the bases, subtract the exponents; if raising the base to another power, multiply the exponents.
x^3 * x^2
x^(2+3) = x^5
(x^5) / (x^2)
x^(5-2) = x^3
(x^3)^2
x^(3*2) = x^6
