Answer:
Neil is 28yrs and his brother is 42yrs old
Step-by-step explanation:
Let r = Neil's brother's age at birth time
2r = Neil's age now
This means that his brother's current age is 3r
So when Neil = 3r old
His brother = 4r old
3r + 4r = 98
7r = 98
r = 14
So their ages now
Neil's brother = 3*14= 42
Neil = 2*14= 28.
Answer:
Yes this is a irrational number
Step-by-step explanation:
Answer:
option A.
Step-by-step explanation:
To solve this, we need to use the following exponent rules:
Quotient rule: (a^n)/(a^m) = a^(n-m)
Power rule: (a^n)^m = a^nm
Power of a product rule: (ab)^n = (a^n)(b^n)
Then, we have the following expressions:
So the correct result is option A.
