Which expression is equivalent to (5x^3)(4x)^3
sergij07 [2.7K]

Answer:

320x^{6}

Step-by-step explanation:

Using the rules of exponents

• (ab)^{n} ⇔ a^{n} b^{n}

• a^{m} × a^{n} ⇔ a^{(m+n)}

simplifying (4x)^{3} = 4³ × x³ = 64x³

(5x³) ×(4x)^{3}

= 5x³ × 64x³ = (5 × 64) × (x³ × x³) = 320x^{(3+3)} = 320x^{6}

What is 3 1/8 - 1/2
irina1246 [14]

Answer:

\frac{21}{8}

Step-by-step explanation:

Given: 3\frac{1}{8} - \frac{1}{2}

Let's changed that mixed number to an improper fraction. Now we get:

\frac{25}{8} - \frac{1}{2}

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

\frac{25}{8} - \frac{4}{8}

We can use \frac{4}{8} because it is equal to \frac{1}{2}. Now, all we need to do is subtract the numerators:

\frac{25}{8} - \frac{4}{8}=\frac{21}{8}

solmaris [256]

Answer:

Surface Area = 150.8 square inch

Step-by-step explanation:

Surface \ Area = 2 \pi r h + 2 \pi r^2  \ \ \ \ \ \ \  \ \ \ \ \ \ [ \ r = 4 , \ h = 2 \ ] \\\\

                    = 2 \pi \times 4 \times 2 + 2 \pi 4^2\\\\=16 \pi + 32 \pi \\\\= 48 \pi \\\\= 150.796 \\\\=150.8 \ square \ inch
