0.25=25/100=1/4. 1/4×84=84/4=21. The answer is 21
Exponents inside the parentheses are done first
eg. 5 + (25- 2) = ?
You would do the numbers inside first
25-2=23 to get 5 + 23 = 28

Answer:
3.482 x 10^9
Step-by-step explanation:
3, 4, 8 and 2 are the only numbers that aren't zero, so they're in the first part of the equation. 3 is the first number, so it goes before the decimal while the others are behind it. There are 9 total spots behind the 3, which is why it's 10 to the 9th power in this notation.
