What value is equivalent to:<br> (8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9???
ankoles [38]

(8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9

Simplify the equations:

(8*4*2/8*7)^2 = (64/56)^2 = (8/7)^2

(8^0/7^-3)^3 = (1/7^-3)^3 = 7^9

Now you have :

(8/7)^2 x 7^9 x 7^-9

Multiply 7^9 x 7^-9 by adding the exponents to get 7^0, which = 1

Now you have:

(8/7)^2 x 1

(8/7)^2 = (8x8) / (7x7) = 64/49

64/49 x 1 = 64/49

1) B. Which method of finding the distance is<br><br> the best? Explain
sveticcg [70]

Answer and Step-by-step explanation:

Distance is the numerical measurement to find the space or interval between two objects. Distance also refers to physical length. Point x to point y  distance is denoted as |xy|

There are many ways to find out the distance, distance between two objects or two points. The efficient way of finding the distance between two points is given below. Mathematically, the distance between two points on a coordinate plane can be determined by using the distance formula, which is:

                                                 d =√((x2-x1)2+(y2-y1)2),

Where (x1, y1) and (x2, y2) coordinates, and d is the distance.

The middle point between these two points is known as midpoint and can find out by using the formula

Midpoint = a + b /2.

The distance between two points number line can also be calculated by using the formula:

AB =|b –a| or |a-b|.
