Question

How do you write $7.4x{10}^{-5}$ in standard notation?

Answer 1

Convert to standard notation:

The number given is $7.4\times {10}^{-5}$

It is $10$ to the power of $-5$ because the exponent is $-5.$

A negative exponent has a solution that is less than the origin or base number.

We shift the decimal five times to the left to arrive at our conclusion:

$7.4\times {10}^{-5}=0.000074$

Hence, the standard notation is $0.000074$.
