The answer for your exact question is
Answer:
214....
Step-by-step explanation:
If the question is : solve 4 by 216 raise to minus 2 by 3 + 1 by 256 raise to minus 3 by 4 + 2 by 243 raise to minus 1 by 5
The given expression can be written as:
4/(216)-2/3+1/(256)-3/4+2/(243)-1/5
This expression has three terms.
Notice that the exponents are negative:
We will change the division into multiplication so that the exponents will become positive;
4*(216)^2/3+ 1*(256)^3/4+ 2*(243)^1/5
If we multiply 6 three times it will give us 6^3=6*6*6=216
If we multiply 4 four times it will give us 4^4=4*4*4*4=256
If we multiply 3 five times it will give us 3^5=3*3*3*3*3=243
So we will write it as:
=4*(6^3)^2/3+ 1(4^4)3/4 +2(3^5)^1/5
=4(6)^2+(4)^3+2(3)
=4*36+64+6
=144+64+6
=214
The answer is 214....
Answer:
a= 52
Step-by-step explanation:
82 + (x+60) + (x+54) = 180
82 + 2x + 114 = 180
2x + 196 = 180
2x = -16
x = -8
plug in -8 in x +60
-8 + 60 = 52
a = 52
Answer:
18 in^2
Step-by-step explanation:
<em>1 )The three sides of the gutter add up to 12</em>
2x+ y = 12
<em>2) Subtract 2x from both sides. </em>
y = 12 — 2x
<em>3 )Find the area of the rectangle in terms of x and simplify.</em>
Area = xy = x(12 — 2x) = -2x^2+12x = f(x)
<em>4 ) x=-b/2a</em>
<em>x co-ordinate of the vertex= -12/2(-2)=3</em>
<em>5 )Plug in 3 for x into they equation.</em>
y co-ordinate of the vertex= 12 — 2(3) = 6
<em>6 ) Plug in 3 for x and 6 for y. </em>
Area= xy = 3(6) = 18
RESULT
18 in^2
