Choose the correct simplification of the expression (2x2y6z5)(5x4y5z3).
10x8y30z15
7x6y11z8
7x8y30z15
10x6y11z8

The correct option is 4.

Step-by-step explanation:

The given expression is

Simplify the given expression.

Therefore correct option is 4.

or

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
