If a=2, b=-3 and c=4, evaluate: b(a-c)^2

1 answer:

5 0

The answer is 36
if you substitute the numbers in, the equation would be..

-3(2-4)^2 so
2-4 is -2
-3 x -2 = 6
and 6^ is the same thing as 6 x 6
so 6^2= 36

Step-by-step explanation:

$\bf \underline{Solution-} \\$

We have to simplify the given expression.

$\rm = \dfrac{ {x}^{a + b} \cdot {x}^{b + c} \cdot {x}^{c + a} }{ {x}^{a} \cdot {x}^{b} \cdot {x}^{c} }$

We know that:

$\rm \longmapsto {x}^{a} \times {x}^{b} = {x}^{a + b}$

$\rm \longmapsto \dfrac{ {x}^{a} }{ {x}^{b} } = {x}^{a - b}$

Therefore, we get:

$\rm = \dfrac{ {x}^{(a + b) + (b + c) + (c + a)}}{ {x}^{a + b + c} }$

$\rm = \dfrac{ {x}^{2(a + b+ c)}}{ {x}^{a + b + c} }$

$\rm = {x}^{2(a + b+ c) - (a + b + c)}$

$\rm = {x}^{a + b + c}$

Two angles are supplementary. if the larger angle is 3 degrees more than twice the smaller angle then how big is each angle. wri

Margaret [11]

Two angles are supplementary when they add up to 180 degrees.

x = smaller angle
2x+3 = larger angle

x + 2x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59° ← smaller angle

2x + 3 = 2*59 + 3 = 121° ← larger angle
