Solution:
Given, Very small numbers can be expressed in standard form by using _________ exponents.
Any number can be expressed as decimal numbers between 1 and 10 multiplied by a power of 10. This form of representation is termed as the standard form.
Example : 0.000045 = 45/100000
0.000045 = 45/10⁵
By laws of exponent a⁻ⁿ = 1/aⁿ
0.000045 = 4.5 × 10⁻⁵
Therefore, Very small numbers can be expressed in standard form by using negative exponents.
