Answer: 7^18/7^9, (7^3)^3 & 7^4 * 7 ^ 5.
The second, third & last options are the answers
These equations equal 40,353,607 btw
1/2 or 50%, because there are two possibilities out of four.
If you think about flipping a coin twice, there are exactly four possible outcomes:
Flip 1 Flip 2
1. tails heads
2. tails tails
3. heads tails
4. heads heads
In two of these possibilities (1 and 3) the coin flipped different sides.
That means 2/4 possibilities matched, and this can be reduced to 1/2
Minus the 10 from the 50, which makes 40. then divide 40 by 8
50-10=40
40÷8=5
n=5
That seems so hard, sending prayers and brain cells to you.
If your question is to write it in scientific notation, it's 10^4 and the exponent is 4
