🧮 Simplify 0.027⁻¹/³ Easily | Step-by-Step Cube Root & Exponent Guide
Question: Simplify 0.027⁻¹/³
Let’s break it down step-by-step with a simple explanation. This concept often appears in algebra and exponent exercises.
🔹 Step 1: Understand the Negative Exponent
A negative exponent means take the reciprocal of the base raised to the positive power.
0.027⁻¹/³ = 1 / 0.027¹/³
🔹 Step 2: Find the Cube Root
We can rewrite 0.027 as a fraction:
0.027 = 27 / 1000
Now, take the cube root of both numerator and denominator:
(27/1000)¹/³ = 3/10 = 0.3
🔹 Step 3: Apply the Reciprocal
Since we had a negative exponent, we now take the reciprocal of 0.3:
1 / 0.3 = 10 / 3
