Answer 1

Answer:

2.40 × 10²

Step-by-step explanation:

Data provided in the question:

we have to convert 820,000 Btu/h to kW

Now,

1 kW = 3412.142 Btu/h

or we can say

1 Btu/h  = 0.00029307107  kW

Therefore,

820,000 Btu/hr in kW will be

= 820,000 × 0.00029307107 =

or

= 240.3182774

or

= 2.40 × 10²

Hence,

according to the question,  X will be 2.4 and the term in the power of 10 is 2
