Step-by-step explanation:
Dividing the numerator and denominator of −924−924 by 3, we get
−924−924 = (−9)÷324÷3(−9)÷324÷3 = −38−38
Thus, the standard form of −924−924 is −38−38.
(ii) −14−35−14−35
The denominator of the rational number −14−35−14−35 is negative. So, we first make it positive.
Multiplying the numerator and denominator of −14−35−14−35 by -1 we get
−14−35−14−35 = (−14)×(−1)(−35)×(−1)(−14)×(−1)(−35)×(−1) = 14351435
The greatest common divisor of 14 and 35 is 7.
Dividing the numerator and denominator of 14351435 by 7, we get
14351435 = 14÷735÷714÷735÷7 = 2525
Hence, the standard form of a rational number −14−35−14−35 is 2
Answer:
x = (-23)+(22)+(-23)+(22)+.. .. .. .. 40 terms
Y = (11)+(-10)+(11)+(-10).. .. .. .. 20 terms
x = 20 pairs of (-23)+(22)= -1
There are 20 pairs so we will get - 1 [20 times]
So, x = - 1×20= -20
Y = 10 pairs of (11)+(-10) = 1
There are 10 pairs so we will get 1[10 times]
So, Y = 1 × 10 = 10
We have to find the value of:-
y - x = 10 - (-20)
= 10 + 20
= 30
