Question

Simplify the following exponential expressions. Explain how. =)

(-5ab)^3

(-8)^0 + 2^0

(x^5)(x^2)( x^3)

(y4)^9

-6^2

Answer 1

1. (-5ab)^3 = -5^3 * a ^ 3 * b ^3 = -15a^3b^3
2. any number ^ 0 always equals 1 so (-8)^0 + 2^0 = 1 + 1 = 2
3. (x^5)(x^2)( x^3) = x ^ (5+2+3) = x^10
4. (y4)^9 = i guess you meant (y^4)^9 = y ^ (9*4) = y ^36
5. -6^2 = 12
