Answer:
3) 3 = x2 + 7x -- 23. (i) zero (ii) one (iii) two (iv) three. Thus, after simplification we can see highest power of x in the above expression is 1. So, the degree is 1.
4) B. 33 ( x + y ) is not a linear equation in one variable. This is because there are two variables x and y in the given equation.
5) Given 2x−1=14−x
⟹2x+x=14+1
⟹3x=15
⟹x= 15/3
⟹x= 5×3/3
⟹x=5
6) If a number has 1 or 9 in the unit's place, then its square ends. Property 4 If a number has a square root in N then its units digit must be `0, 1, 4 ,5 ,6or 9`.
7) n2
The first n odd natural numbers are given by 1,3,5,7,9…… (2n – 1) and this forms an AP. The sum of first n odd natural numbers is n2.
8) 21
9) From the above examples we can say that the cube of an even number will always be an even number and the cube of an odd number will always be an odd number. So, the correct answer is “Option A”.
10) 1729 is sometimes called the “Hardy-Ramanujan number”.
