(7*10^5)^2 simplified in scientific notation

coldgirl [10]

♥ Lets solve this:
(7*10^5)^2(7*10^5)^2
Starting with 10^5
10*10*10*10*10
We get 100000
Now we have 7*100000
Solve for that:
We get 700000
Now we have 700000^2
Solve for that
We get 490000000000
and in Scientific notation that is
4.9*10^11

A pair of boots is 30dollars more than a pair of sandals. A pair of sandals cost s dollars each. Emily purchased 2 pairs of boot

babunello [35]

Answer: The expression representing the amount of money spent is $5x+60$ by Emily.

Step-by-step explanation:

Since we have given that

Let the cost price of per pair of sandals be 's'

Let the cost price of per pair of boots be 's+30'.

Number of pairs of boots = 2

Number of pairs of sandals = 3

Total cost would be

$2(s+30)+3s\\\\=2s+60+3s\\\\=5s+60$

Hence, the expression representing the amount of money spent is $5x+60$ by Emily.
