please mark me as brainliest
Yes, Both are equivalent.
<u>Step-by-step explanation:</u>
Step 1:
To find the equality between the given terms Use the BODMAS (Brackets Orders Division Multiplication Addition Subtraction)
RHS SIDE:

Equation after 1st modification

Equation after Second modification

Equation after Third modification
LCM 2,4,8 is 8
And taking LCM equation changes to 
Equation after Final modification
--------- 1
Step 2:
LHS SIDE:

By applying the BODMAS rule in the above equation we will get
------------ 2
From equations 1 & 2, the expression
is equivalent to 
Answer:

Step-by-step explanation:
using the properties of logarithms, the log of a product gives the addition of logs, and the log of a quotient gives the subtraction of logs;

The exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12
<h3>How does scientific notations work?</h3>
The number is written in the form
where we have 
The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).
Scientific notations have some of the profits as:
- Better readability due to compact representation
- Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.
Expressing the multiplication of (9.1 × 10^9)(7.5 × 10^2) in terms of scientific notation, we get:
(the exponent is 12)
Thus, the exponent of the power in the scientific notation of the result of the expression (9.1 × 10^9)(7.5 × 10^2) is 12
