Answer:
108,000,934
1.08934×10^8
Step-by-step explanation:
(302)^3
(a+b)^3
(a+b)^3==a^3+3a^2b+3ab^2+b^3
(300+2)
(300)^3+3(300^2+2)+3(300+2^2)+2^3
27,000,000+81,000,002+8+924
108,000,002+8+924
108,000,934 or 1.08934×10^8
<span> The product of two perfect squares is a perfect square.
Proof of Existence:
Suppose a = 2^2 , b = 3^2 [ We have to show that the product of a and b is a perfect square.] then
c^2 = (a^2) (b^2)
= (2^2) (3^2)
= (4)9
= 36
and 36 is a perfect square of 6. This is to be shown and this completes the proof</span>

Answer:

Step-by-step explanation:
$1800 is spent on a washing machine. This number never changes, so we just need to add that to our annual total
