Question

What are some examples of scientific notations on a scientific calculator?

Answer 1

Hint: On a normal calculator we cannot solve the value for $\dfrac{4.58\text{ x 1}{{\text{0}}^{8}}}{8.2\text{ x 1}{{\text{0}}^{2}}}$, but in scientific calculator this is easily possible. In many electrochemical, kinetics, equilibrium, etc questions we need the values of log, which is also possible in scientific calculators.

Complete answer:
Normally we use a calculator in which we can get the values for addition, subtraction, multiplication, division, percentage, etc for simple values. But if you want to calculate the value for $\dfrac{4.58\text{ x 1}{{\text{0}}^{8}}}{8.2\text{ x 1}{{\text{0}}^{2}}}$, then it will be very difficult and the chances of error is very common. For this, we can use a scientific calculator. There is a feature in the exponential in the scientific calculator which can be easily used to write numerical in the form of $4.5\text{ x 1}{{\text{0}}^{8}}$, so, this can written as 4.5E8, E is used to express $\text{x 1}{{\text{0}}^{\hat{\ }}}$ .
There is a feature of log and antilog in the scientific calculator that can be easily used to find any log and antilog value by taping the log or antilog button and entering the value needed.
We can easily find the root of numbers also on the scientific calculator. In finding the trigonometric values like sin, cos, tan, etc. We may know some value of the trigonometric ratios like at angles 0, 30, 45, 60, and 90. But if we want to know the value of $\sin {{5.2}^{\circ }}$, then this can be done by a scientific calculator just entering a value.

Note:
In some scientific calculators, the conversion is there where we can convert the length, temperature, weight, etc like if the temperature is given in degrees Celsius we can convert it into Kelvin.
