Perfect questions for guys interested in maths..

2. The value of x + x(xx) when x = 2 is:

(a) 10, (b) 16, (c) 18, (d) 36, (e) 64

Solution:

x + x(xx)

Put the value of x = 2 in the above expression we get,

2 + 2(22)

= 2 + 2(2 × 2)

= 2 + 2(4)

= 2 + 8

= 10

Answer: (a)

Answer 2

Answer:

Answer Is 2%.

Explanation:

Since, we know the formulae of the area is known to be length × breadth. So, the the error in the length and breadth separately will be L × B or delta L + delta B where the value of the length and breadth error are 1% respectively.

So, the error in the area will be 1+1= 2%. Since, there are no multiple or power of the variables hence the error will be same.
