Multiply 2^(9)*2^(2)*2^(4)
Flauer [41]

Answer:

2 ^ 15

Step-by-step explanation:

2 ^9  * 2 ^ 2   * 2 ^ 4

When we multiply numbers with the same base, we can add the exponents

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

2 ^9  * 2 ^ 2   * 2 ^ 4

2 ^ ( 9+2+4)

If you help I will give you brainliest
hammer [34]

9514 1404 393

Answer:

  5 miles

Step-by-step explanation:

Time/speed/distance problems can be worked a number of ways. Here, we want to know the distance walked. We know the total time and the total distance and the two different speeds. So, we can use a variable to represent the value we want to know: w = distance walked (in miles).

The total time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours.

The total time is the sum of times for the two parts of the trip: walking and riding.

  walking time = walking distance/walking speed

  = w/3

  riding time = riding distance/riding speed

  = (20-w)/30

The total time is that given above:

  w/3 +(20-w)/30 = 13/6

  10w +(20 -w) = 65 . . . . . . . . multiply by 30

  9w = 45 . . . . . . . . . . . . subtract 20, collect terms

  w = 5 . . . . . . . . . . . divide by 9

The girl walked 5 miles.

Which number is bigger: 0.135 or 0.14?
Fofino [41]
0.14 as if you convert it into like decimal (add a 0 if the places are not the same e.g. 0.1 and 0.02 here 0.1 does not have the same number of digits so add a zero so it becomes 0.10 :. 0.10 is bigger then 0.02) (note the value of 0.1 will remain the same) so here 0.14 will become 0.140 :. bigger than 0.135

\sqrt{50d^{10}} \\\sqrt{50} =5\sqrt{2}\\5\sqrt{2} *\sqrt{d^{10}}  \\5\sqrt{2}*d^{10/2} \\5\sqrt{2} d^{5}


That's about as much as you can simplify this problem.

I hope this helps! :)
