Answer:
First answer: "Add the exponents"
Step-by-step explanation:
The laws of exponents include the following for product of exponents with the same base:

which implies addition of exponents
So you need to add exponents
The general term of an arithmetic sequence is,

Where ,
= nth term.
= First term
and d = common difference.
The given sequence is: 57, 66, 75, 84, 93, ...
Here
= 57,
d = 66 - 57 = 9
We need to find the 250th term. So, n = 250.
Next step is to plug in these values in the above formula. Therefore,

= 57 + 249 * 9
= 57 + 2241
= 2298
Therefore, 250th of this sequence is 2298
Hope this helps you!
The formula to find the volume of cube
cube = s^3
Therefore volume is equal to I^3
The second cube has 4x the First cube
4 × (I^3) = 4 ×I^3
Total volume of the second cube= 4I^3 cm3
Fact: the density(mass ÷ volume) of aluminium is 2.40g/cm3
Making mass the subject of the formula:
D = M ÷ V
(Times volume to remove deno minator)
Mass = Density × Volume
Mass = 2.40 × 4I ^3
Mass = 8.40I^3
By physics
weight= m × g
where
M = mass
g = acceleration due to gravity (= 9.8)
W = 8.40 I^3 × 9.8
Weight of aluminium = 82.32I^3
