Question

What is the cube root of -729a^9b^6?

Answer 1

Explanation:

- ³√-729 = -9 → [-9]³

- ³√a⁹ = a³ → [a³]³ (MULTIPLY the exponents)

- ³√b⁶ = b² → [b²]³ (MULTIPLY the exponents)

**On my channel, I have a video that talks about six unique Rational Exponential Rules. This would qualify because in each set of parentheses, I put "MULTIPLY the exponents". This is part of an exponential rule.

Answer 2

A

Step-by-step explanation

³√-729a⁹b⁶

³√-729 * ³√a⁹ ³√b⁶ (reduce the index of the radical and exponent with 3)

-³√729a³b²

-³√9³ a³b²

-9a³b²
