0.7 Liters and 0.70 Liters are the same amount.
You can think of them as fractions: 7/10 and 70/100. Both of these mean the same. 7/10 is the simplest form of the number.
When you put zeros to the right of any number that is to the right of the decimal point, it will not change the value of the number.
0.7 L = 0.70 L
1 = 90
2 = 65
3 = 65
4 = 25
90+25=115
180-115=65
have a merry christmas :)
explanation:
There isn't an exact way to answer this problem. Is there more to the question? If not, I am unable to answer it for you.
Answer:
It is +2 or since (+2)*(+2 ) gives. If you think that it would be (-2) also then you are wrong because root of a positive rational number is always positive number.
Step-by-step explanation:
Let the square root of four be ‘k’.
Then we have
(4)^1/2=k
(Squaring both sides)
4=(k)^2
=>(k)^2–4=0
=>(k)^2-(2)^2=0
=>[k+2][k-2]=0 {since (a)^2-(b)^2=(a+b)(a-b)}
if product of two numbers is 0 then either of one must be zero.
If k+2=0 then k=-2
If k-2=0 then k=2
From here we got two answers but -2 should be omitted because when we square an equation we add “root extra”which means that when we square an equation one root is added.
