Answer
$$ 52.42 = 5.242\cdot 10^{1} $$
Explanation
Step 1: Move the decimal point from its current position (the black dot) to a position immediately to the right of the first nonzero digit (the red dot).
5.2.42
Step 2: We moved the decimal point 1 spaces to the right. Therefore, the exponent on base 10 will be positive 1.Now we know that the:
Mantissa = 5.242
Exponent = 1
