Answer 1

Answer and

Step-by-step explanation:

41. If the number of men is equal to the number of women then the value of x will be (c) 8 in roughly guessing.

And if it is written in a equation then it will be

√(9+2x)-√2x=5/√(9+2x)

or, √(9+16)-√16=5/√(9+16)

or, √25-4=5/√25

or, 5-4=5/5

or, 1=1.

Hence, the value of x will be (c)8.

42. (-3)^-4=1/81

So, the correct option is (d)1/81.

43.(a) a^p+q

44. The image is too blurred but if the sign is + then you can use the take base common and add their powers and the will be your answer.

For example: 7^1.2+7^2.2=(7)^(1.2+2.2)=7^3.4.

45. (b) r-s is a rational number.

Is a false statement.

For example: 1-1/2=1/2 whose difference is a irrational number.
