Answer:
4^5
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
1/a^b = a^-b
__
Then you have ...
(4^8)/(4^3) = (4^8)(4^-3) = 4^(8-3) = 4^5
Don't know how to type the symbole infront of the 50 so I will subsitute
£50=$50
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
