Answer:

Step-by-step explanation:

256 = 16×16=4×4×4×4 = 4^4

X^4-4^4 = (x^2)^2 - (4^2)^2

Using algebraic identity a^2-b^2 = (a+b)(a-b)

We get (x^2+4^2)(x^2-4^2)

(x^2+4^2)(x+2)(x-2)

2/-3 divided by -1 2/7 = <br> pls explain the answer

katen-ka-za [31]

Answer:

$\frac{14}{27}$

Step-by-step explanation:

$-1\frac{2}{7} = -\frac{9}{7}$
Plug -9/7 in: $-\frac{2}{3}$ ÷ $-\frac{9}{7}$
-2/3 ÷ -9/7 = 2/3 ÷ 9/7 = 2/3 × 7/9
$\frac{2}{3}$ × $\frac{7}{9} = \frac{14}{27}$

I hope this helps!

PLEASE HELP QUICKLY : find the sum and difference of 5/6 and 1/2

choli [55]

Hello!

The sum of 5/6 and 1/2 is 1 1/2

5/6 > 3/4 so round it to 1.

1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.

Estimating:

1 + 1/2 = 1 1/2

The difference of 5/6 and 1/2 is 1/2

5/6 > 3/4 so round it to 1.

1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.

Estimating:

1 - 1/2 = 1/2

Hope this helps!
