Answer:

2*x^3 + x^2 + x

Step-by-step explanation:

a^b = x

Then,

a^(2b) = a^b*a^b = x* x = x^2

a^(3b) = a^b*a^b*a^b = x*x*x = x^3

2*(a^3b) + (a^2b) + (a^b)

= 2*(x^3) + (x^2) + (x)

= 2*x^3 + x^2 + x

Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know.

stepladder [879]

Answer:

Less than 1

Step-by-step explanation:

As 0.644 and 0.25 are less than 1, then

$0.644=\frac{1}{p}$

$0.25=\frac{1}{q}$

where p and q are greater than 1

then

$0.644\times0.24=\frac{1}{p.q}$

But p.q is greater than 1, so 1/(p.q) is smaller than 1
