Answer:

53

Step-by-step explanation

8 - 8/2 (this is a fraction) is also known as

8-4 because 8 divided by 2 is 4

so 8-4 = 4

next 4 + 7^2

why is the 2 in the air????

so that's called an exponent, in this case the two means 7 x 7, it is multiplying by itself, thats the essence of exponents. I can do this for exponent 3,4,5,6,7 and so forth. Anyways, 7^2 or 7x7=49

Knowing this its now 4+49= 53

X²+2xy+y²=144, (x+y)³?​
Bumek [7]

Answer:

The value of (x + y)³ is 1728.

Step-by-step explanation:

First, you have to find the value of x + y :

x² + 2xy + y² = 144

x² + xy + xy + y² = 144

x(x + y) + y(x + y) = 144

(x + y)(x + y) = 144

(x + y)² = 144

x + y = √144

x + y = 12

Next, the value of (x + y)³ :

(x + y) = 12³ = 1728
