5 x (8 x 10 with the power of 4)
ella [17]
First you need to solve the stuff in the parenthesis.
8 x 10^4

10^4 = 10,000

8 x 10,000 = 80,000

80,000 x 5 = 400,000

The answer is 400,000

Alika [10]
C ÷ D- EXPRESSION
-24÷1/4=-18
24
- 6
---------
18

The answer​ is negative because when you divide 24 by 4 you get 6. and since the number 24 is negative.you need to subtract 6 from 24 to get -18 which is negative.

P.S:I am a 6th graders who doesn't really understand negatives, but i tried my best and got this answer.

Please help!!! &lt;3 Thanks! Rewrite the equation by completing the square. <img src="https://tex.z-dn.net/?f=4x%5E2-4x%2B1%3D0%
Xelga [282]

Answer:

(2x - 1)^2

Step-by-step explanation:

We can reverse engineer the solution...

to complete the square, we know (2x + __)^2 will generate the 1st term 4x^2

To generate the 2nd term, we will need -1, so (2x - 1)^2....

When expanded, we will have 4x^2 - 4x + 1, which we completed the square.
