Write 0.0763 correct to one significant figure

The number in decimals, 0.0763 has 3 significant digits.As, digit 0 which is appearing before 7 has no significant value.

So, Number 0.0763 expressed in one significant figure= 0.078

Why i have written this, because the digit  7 is greater than 5 , so 763 will correspond to 800.

So, 0.0763 = 0.0800=0.08

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.
