Question

please help Select all the correct answers.Jim writes down a large number. The number is 543 followed by 12 zeroes. How would Jim express this number in scientific notation?5.43 × 10145.43 × 10-125.43E145.43 × 10125.43E105.43 × 10105.43E-125.43E12

Answer 1

Given that 543 is followed by 12 zeroes, then 12 is the exponent of 10, as follows:

$543\cdot10^{12}$

Dividing and multiplying this number by 100, we get:

$543\cdot10^{12}=543\cdot10^{12}\cdot\frac{100}{100}=\frac{543}{100}\cdot10^{12}\cdot100=5.43\cdot10^{12}\cdot10^2=5.43\cdot10^{14}$

This expression is equivalent to 5.43E14
