Answer:
22×10⁻¹³
Step-by-step explanation:
Scientific notation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example the number 6324.4 in scientific notation will be written as = 6.3244 × 10³
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value. Thus, in given value,
(4.1357× 10⁻¹⁵) × (5.4×10²)
22×10⁻¹³
