Simplify each expression.<br> (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃
babymother [125]

The result of simplifying each number (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃  using the exponent rules is -3

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃

Using the product rule that indicates that: the exponent result will be the addition of these exponents, we have:

(-3)¹/₃⁺ ¹/₃ ⁺ ¹/₃

(-3)³/₃

(-3)¹

-3

<h3>What is an exponent?</h3>

Answer:

2x\sqrt{40x}-2x\sqrt{5}

Step-by-step explanation:

2x\sqrt{40x}-2x\sqrt{5} is found by first, siplifying the radicals in the parenthesis. \sqrt{8x^{2} } can be simplified as 2x\sqrt{2} and -2\sqrt{x} stays the same. Now we have to multiply these two by \sqrt{5x} which then results in 2x\sqrt{40x}-2x\sqrt{5}
