Answer:
4.60095 * 10^7
Explanation:
46009500 = _ * 10^ _
Place the decimal point after the 4.
4.6009500
Now, in the original number, starting from the rightmost digit, count the number of places the decimal point moved to the left.
The decimal point was here, to the right of the last zero: 46009500.
Now it's here, to the right of the 4: 4.6009500
It moved 7 places to the left, so the exponent of 10 is 7.
46009500 = 4.60095 * 10^7
