Ben is 3 times as old as Daniel and is also 4 years older than Daniel. How old is Daniel?

1 answer:

5 0

B=3d and b=d+4

Since b=b we can say:

3d=d+4 subtract d from both sides

2d=4 divide both sides by 2

d=2

Daniel is 2 years old. (and Ben is 6 years old)

Answer:
1/625

Explanation:
In case of multiplication of numbers with same base, we add the powers.
This means that:
a^x * a^y = a^(x+y)

Applying this to the given, we will find that:
(5^-1) * (5^-3) = 5^(-1-3)
= 5^-4
= 1/625

Hope this helps :)
