Write a multiplication expression using the following clues:
One factor is a two digit number between 1 and 10
One factor is a two digit number between 1 and 10 (different from the first)
The product is greater than 8, but less than 10

3.5*2.5=8.75

Step-by-step explanation:

3.5 and 2.5: two digit numbers

8.75: between 8 and 10

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
