answer: 6.4
work:
Solve the problem.
Let's start by solving the numerator,
(5 + 3)² <em>step one: add 5 + 3 </em>
(8)² <em>step two: simplify 8²</em>
64
now, let's simplify our denominator
1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>
1 + 32 - 23 <em>step two: add 1 + 32.</em>
33 - 23 <em>step three: subtract 33 - 23</em>
10.
now, put the numerator back over the denominator.
64/10
let's simplify by dividing, we get 6.4.

Answer:
x = 1.27
y = 5.18
Step-by-step explanation:
to solve this system of equation by simultaneous equation we say that let
3x+y=9.............................. equation 1
-5x+2y=4 .......................... equation 2
from equation 1
3x+y=9.............................. equation 1
y = 9 -3x.............................. equation 3
substitute the value of y = 9 -3x into equation 2
-5x+2y=4 .......................... equation 2
-5x + 2( 9 -3x) = 4
-5x + 18 - 6x = 4
collect the like terms
18 - 4 = 6x + 5x
14 = 11x
divide both side by 11
14/11 = 11x/11
x = 14/11
x = 1.27
put the value of x = 1.27 into equation 3
y = 9 -3x.............................. equation 3
y = 9 - 3( 1.27)
y = 9 - 3.82
y = 5.18
<em>to check if you are correct put the value of x and y into either equation 1 or equation 2.</em>
<em>3x+y=9.............................. equation 1</em>
<em>3( 1.27) + 5.18 = 9</em>
<em>3.81 + 5.18 = 9</em>
<em>9 = 9</em>
