The value of b is 4
Step-by-step explanation:
The form of an exponential function is 
, where
- a is the initial value (value f(x) at x = 0
- b is the growth/decay factor
- T find the values of a and b substitute x and f(x) by the coordinates of any points belong to the function
∵ 
∵ The function includes the points (2 , 16) , (3 , 64) , (4 , 256)
- To find b substitute x and f(x) by the coordinates if any point above
∵ x = 2 and f(x) = 16
∴ 
- Take √ for both sides
∴ ± 4 = b
Substitute x by 3 and f(x) 64 to check your answer
∵ 
- Take ∛ for both sides
∴ 4 = b
∴ The value of b is 4 only
The value of b is 4

3/15=?/315
divide 315 by 15
then take that number and multiply that by three
then that THAT number and put it over 315
then simplified

Ratio can be rate but rate can never be ratio. In essence, rate is comparison between ratios. While ratio is comparison between two or more numbers. Further, ratio on one hand, involves numbers either in amount, size, measurement, degrees, percentages or fractions with the absence of specific unit of measurement. On the contrary, rate is comparing quantities, amounts or unit of events happened expressed in a specific measurement or expressed under time. Take for instance, an example, Joe eats 2 while John eats 4 meals in a day. The ratio can be Joe: John, 2:4 meals. While the rate, is Joe eats 2 meals/day and John 4 meals/day.
Answer:
18√7x⁶
Step-by-step explanation:
Given the expression 7√28x⁶+4√7x⁶, we are to fund the sum in its simplest form as shown;
7√28x⁶+4√7x⁶
= 7√(7*4)x⁶+4√7x⁶
= 7*2√7x⁶+4√7x⁶
= 14√7x⁶+4√7x⁶
Factor out the like term
= 2√7x⁶(7+2)
= 2√7x⁶(9)
= 18√7x⁶
Hence the sum is equivalent to 18√7x⁶
