Step-by-step explanation:
A rational number can be expressed in the form
where a and b are integers ( b ≠ 0 )
12= 
⇒ rational
- 
→ is irrational
- 
⇒ rational
6.8 = 6 
= 
⇒ rational
Step-by-step explanation:
4⁵ × 4^-7 / 4^-2
it is important to understand that a negative exponent means 1/...
a^-n = 1/(a^n)
in that sense we have therefore
4⁵ × 1/4⁷ × 4² (as (1/ 1/a^n) = a^n)
4⁵ × 4² × 1/4⁷ = 4⁷ × 1/4⁷ = 1
so, "1" is the fully simplified expression equal to the original expression.
Answer:
402.00$
Step-by-step explanation:
Just multiply the amount by the cost?
Use the formula i = p*r*t.
Here, p = $100000, r = 0.05 and t = 1 (year)
The interest would be i = $100000*0.05*1 = $5000 per year.
