23.2 repeating + sqrt 16 is rational because repeating numbers are rational and sqrt 16 is rational.
Answer:
589.4 cubic inches.
Step-by-step explanation:
The volume of the cube with each side of the measure of 9.5 inches.
So, the volume of the cube will be (9.5 × 9.5 × 9.5) = 857.375 cubic inches.
Now, if there is a ball inside this cube with volume 268 cubic inches then the remaining volume inside the cube is filled with air.
Therefore, the volume of air inside the cube will be (857.375 - 268) = 589.375 cubic inches ≈ 589.4 cubic inches. (Answer)
Answer:
√x
Step-by-step explanation:
Step 1: First, simplify -3⁄6 to -½.
Step 2: According to the Negative Exponential Rule, you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM NEGATIVE TO POSITIVE:
bⁿ = 1\b⁻ⁿ
1\x-¹\² = x¹\²
Step 3: Again, using the Definition of Rational Exponents, rewrite this rational exponent as a radical:
x¹\² = √x
