Answer:
Step-by-step explanation:
This is hard to explain, but basically you use exponent rules to switch it to an exponent
It's easiest if you calculate first
4³ = 4 x 4 x 4 = 48
Then convert the root to a fraction exponent
Combine them using addition, since addition was in the problem

So we know that there are 1000 mL in 1 L. We can set up an equation that allows us to solve for how many bottles are needed in order to empty the 30 L tank:
This equation then allows us to cancel out the units of mL and L, leaving us with how many bottles are needed per tank. Then we multiply straight across to give us:
The question asks us to round up to the next whole number, so it would take 86 bottles to empty one 30 L tank.

The Factorization of 121b⁴ − 49 is (11b^2 + 7)(11b^2 - 7).
The equation 121b⁴ − 49
To find the Factorization of 121b⁴ − 49.
<h3>What is the factor of a^2-b^2?</h3>
The factor of a^2-b^2 is (a+b)(a-b)
We have write the given equation in the form of a^2-b^2
Therefore the factor of the 121b^4 − 49 is (11b^2 + 7)(11b^2 - 7).
