Which expression is equivalent to (5x^3)(4x)^3

sergij07 [2.7K]

Answer:

320 $x^{6}$

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) = 320 $x^{(3+3)}$ = 320 $x^{6}$

Alex Ar [27]

Answer: 96 pounds

Step-by-step explanation:

Let x be the number of pounds of $6 nut required .

then you know the weight of the resulting mixture = (x+32)

The total cost of the mixture= $5(x+32)$

According to the question,

$5(x+32)=32\times2+6x\\\Rightarrow\ 5x+160=64+6x\\\Rightarrow\ 6x-5x=160-64\\\Rightarrow\ x=96$

Hence, Randall must use 96 pounds of $6 nuts.
