Ineed with multiplication properties of exponents i've tried to solve both problems repeatedly and i cannot solve them. i really need to redo the assignment so any is welcome! p. s. my teacher said on the assignment that the first one is going to be a negative.

1) x= -36.

2) x = 0.

Step-by-step explanation:

1) Taking the 3rd power to both sides and using the following exponent law:

we get:

So this tells us that x = -36.

2) We can distribute the power inside every term. So the left side becomes:

Now, the trick here is to remember that , so replacing 1 with , which then gives us:

, telling us that 3x = 0 and thus, x = 0.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

40 minutes

step-by-step explanation:

add the time and multiply by 2
