What is the same as moving the decimal point 3 places to the left in a decimal number ? 1. Multiplying the number by 1,000
2. Dividing the number by 1,000
3. Multiplying the number by 100
4. Dividing the number by 100

Step-by-step explanation:

Every time you move the decimal, add a zero. Since the decimal is moved three times, there are three zeroes. When you move left, the number is getting smaller so it is division.

10

step-by-step explanation:

7+3=10

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!
