Step-by-step explanation:
5×6'3n=20
30'3n=20
3n=20-30
3n/3= -10/3
n= -3
I'm assuming you meant to write a^4 = 625.
If that is the case, then note how 625 = 25^2, and how a^4 is the same as (a^2)^2
So we go from this
a^4 = 625
to this
(a^2)^2 = 25^2
Apply the square root to both sides and you'll end up with: a^2 = 25
From here, apply the square root again to end up with the final answer: a = 5 or a = -5
As a check:
a^4 = (-5)^4 = (-5)*(-5)*(-5)*(-5) = 25*25 = 625
a^4 = (5)^4 = (5)*(5)*(5)*(5) = 25*25 = 625
Both values of 'a' work out
Answer:
It makes sense to me but I don't know if anyone else agrees
Step-by-step explanation:
Answer:
0.51 liters in the glass
Step-by-step explanation:
Given
Required
Determine how many liters in the glass
To do this, we simply multiply the fraction poured by the total.
So, we have:
<em>There will be 0.51 liters in the glass</em>
