<u>Simplifying the expression:</u>
Let us determine how the expression can be simplified.
The expression is given by
Applying the exponent rule that in the above expression, we get;
Adding the exponents, we get;
Again, applying the exponent rule , we get;
Thus, the simplified expression is
Hence, the expression is simplified by adding the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.
Therefore, Option D is the correct answer.
Area of the shaded region square cm
Perimeter of the shaded region cm
Solution:
Radius of the quarter of circle = 12 cm
Area of the shaded region = Area of quarter of circle – Area of the triangle
square cm.
Area of the shaded region square cm
Using Pythagoras theorem,
Taking square root on both sides of the equation, we get
cm
Perimeter of the quadrant of a circle =
cm
Perimeter of the shaded region = cm
cm
Hence area of the shaded region square cm
Perimeter of the shaded region cm
