The correct answer is: (Option B)
Explanation:
Given expression:
Take square-root of the expression:
Evaluate the resultant expression:
Hence the correct answer is option (B) .
Answer:
It is not.
Step-by-step explanation:
See, lets do simplification
30 divided by 10 = 3
54 divided by 10= 5.4
3:5 is not equal to 3:5.4
Answer:
Step-by-step explanation:
Starting point:
1) Factor it by Prime Factor Method 72 and 50
2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.
3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.
x^2 + 3x = 10
Answer:
Step-by-step explanation:
We shall use middle term split method to find the factor
here middle term is 3 ,factor of -10 which gives -3 on adding
such numbers are -10 = 5 and -2
5+(-2) = 3
And then making two groups and simplifying it ,we get the roots
Answer:
There are so many!
For circumference use = 2 pi r
For area use = pi r²
I have told only formula, else you may lack practice. try to solve yourself
B. 27x1/27x2
C. 3x3x3/3x3x3x2
D. 1/2
Answer: C. 27/54 .
Step-by-step explanation:
Here, given number, 27/54
Since the prime factor form of 27 =
And, the prime factor form of 54 =
putting the prime factor form of both 27 and 54 in the given numbers.
we get,
Thus, by putting the prime factor form by C we get the simplest form of the given fraction.
Therefore, Option C is correct.
