Answer: 8.70%

Step-by-step explanation:

Percent error is calculated as:

= (Accepted value - Experimental value) / Accepted value × 100

= (23 - 21) / 23 × 100

= 2/23 × 100

= 8.70%

The percentage error is 8.70%

Evaluate the following expression will give branliest<br> 256 to the power of 5/8

Nana76 [90]

Answer:

32

Step-by-step explanation:

The formula needed to solve this question by hand is:

$x^{\frac{m}{n}} =\sqrt[n]{x^{m}}$

256^(5/8) = 8th root of 256^5

256^(5/8) = 8th root of 1280

<u>256^(5/8) = 32</u>

What’s the pattern of -1, -8, -27, and -64

AURORKA [14]

Hello from MrBillDoesMath!

Answer:

a(n) = (-n)^3 where n = 1,2,3,...

Discussion:

The pattern 1,8,27, 64... is immediately recognizable as the the cube of the positive integers. But this question has a minus sign appearing before each entry, suggesting we try this:

- 1 = (-1)^3

-8 = (-2)^3

-27 = (-3)^3

-64 = (-4)^3

That's what the problem statement asked for . The answer is equivalently

-1 * (n^3)

Thank you,

MrB
