Answer:

8 x^-2

Step-by-step explanation:

2 sqrt(x) * 4x ^ -5/2

Rewriting

2 x^1/2 * 4x ^ -5/2

2*4 = 8

x^1/2 * x^ -5/2

We know a^b * a^c = a^(b+c)

x^ 1/2 * x^ -5/2 = x^ (1/2 -5/2 ) = x^ (-4/2) = x^-2

8 x^-2

Camacho is buying a monster truck. The price of the truck is xx dollars, and he also has to pay a 13\%13% monster truck tax.

Maslowich

Answer:

$1.13x$

Step-by-step explanation:

We have been given that Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. We are asked to find the total amount paid by Camacho for the monster truck.

The total cost of monster truck would be x plus 13% of x.

$\text{The total cost of monster truck}=x+\frac{13}{100}x$

$\text{The total cost of monster truck}=x+0.13x$

$\text{The total cost of monster truck}=1.13x$

Therefore, Camacho paid $1.13x$ dollars in total for the truck.
