Answer:
2.25 × 10^1 and It has 3 significant figures. In scientific e-notation it is written as 2.25e+1.
Explanation:
1) Move the decimal 1 times to left getting m = 2.25, is greater than or equal to 1 but less than 10
2) Since we moved the decimal to the left the exponent n is positive n = 1
3) Write in the scientific notation form, m × 10n = 2.25 × 10^1
