8 ^ 2013 times (- 0.125) ^ 2012=___ ?

Hello!
8 ^ 2013 times (- 0.125) ^ 2012
=8 times 8 ^ 2012 times (0.125) ^ 2012
=8x（8x0.125）^2012
=8x1^2012
=8
If you don't understand, you can ask. If it helps, remember to adopt it,
Thank you and wish you progress in your study!

If 2013 of 1.8 times 2014 of 0.125 2. A plus 1 / 2 of a equals 8, then the power of a plus 1 / 2 of a equals 3
If we know that x + y equals minus 5, XY equals 6, then the square of X is equal to 5. Calculate the square of a (1 minus a) plus (a plus 1) minus 1. Thank you very much

2013 of 1.8 times 2014 of 0.125
=8 to the power of 2013 × 0.125 to the power of 2013 × 0.125
=(8 × 0.125) to the power of 2013 × 0.125
=0.125
2. If a plus one part of a equals 8, then the power of a plus one part of a equals 8
a+1/a=8
Two sides square
a²+2+1/a²=64
∴a²+1/a²=62
3 XY times (2Y + X-Y & # 179;) equals the power of 2XY plus the power of X, y minus XY4
4. If we know that x plus y is negative, 5xy is 6, then the power of X and the power of Y is equal to 6
x²+y²=(x+y)²-2xy=(-5)²-12=13
5. Calculate the square of a (1 minus a) plus (a plus 1) minus 1
a(1-a)+(a+1)²-1
=a-a²+a²+2a+1-1
=3a

A car is 80 kilometers per hour, and a truck is 60 kilometers per hour. They are separated by 40 kilometers. It takes a few hours for the car to catch up with the truck in front

40/(80-60)=2

a. Then (a + b) 3-3 (CD) 4=______ ．

According to the meaning of the question: a + B = 0, CD = 1, then the original formula = 0-3 = - 3

A and B vehicles travel from both places at the same time. Car a travels 45 kilometers per hour, while car B travels 42 kilometers per hour. They meet 12 kilometers from the midpoint,
Can you tell me how many hours after the two vehicles leave at the same time, they meet? (please tell me why the distance difference between the two vehicles is 24, isn't it 12?)

Encounter time: 12 × 2 △ 45-42 = 8 (hours)
Because when car a and car B meet, car a is 12 kilometers above the midpoint, and car B is 12 kilometers away from the midpoint. Therefore, the distance difference between car a and car B is 12 × 2 = 24 (km)

To solve the equation X-7 / 2x = 4 / 3

X-2/7X=3/4
5/7X=3/4
20X=21
X=21/20

Party A and Party B are 25km apart, and they are facing each other at the speed of 4.5km/h and 5.5km/h respectively. At the same time, the dog with a runs to Party B at the speed of 7.5km/h, returns to Party A quickly after meeting Party B, and runs to Party B again when meeting Party A And so on, until Party A and Party B meet, ask: how far does the dog run

The distance the dog runs
=【25÷（4.5+5.5）】×7.5
=2.5×7.5
=18.75 km

The two cars drive from a and B at the same time and face each other. They meet 4 hours later. It is known that a travels 50 kilometers per hour and B 60 kilometers per hour. It is necessary for a to complete the whole journey
How many hours does an auditorium need to be paved with 9dm2 granite plate? 9600 pieces are needed. If it needs to be paved with 16dm2 granite plate, how many pieces are needed? (use proportion solution)

1. A needs to drive 60 × 4 = 240 km
A: 240 / 50 = 4.8 hours
2. A block is needed
9600：a=16：9
16a=9600×9
A = 5400
1. It will take an hour to set up a computer
The time ratio is equal to the inverse of the speed ratio
50：60=4：a
50a=240
A = 4.8 hours
