To add the numbers given in standard form, we first convert them into numbers with __ exponents. Fill in the blank to make the statement true.

Solution:

Given, To add the numbers given in standard form, we first convert them into numbers with __ exponents.

Consider two numbers in standard form,

Let the numbers be 23 × 10⁴ and 2.3 × 10⁵

Adding the numbers, we get

23 × 10⁴ + 2.3 × 10⁵

On making the exponents equal, we get

= 23 × 10⁴ + 23 × 10⁴

= 2(23 × 10⁴)

= 46 × 10⁴

Therefore, to add the numbers in standard form we have to convert the numbers with equal exponents.
