Answer:
a= 38.85
Step-by-step explanation:
So to multiply standard form we multiply the 2 numbers and the 2 indices separately.


So we've got

However Standard form must be

therefore we need to divide that by 10 but to get the same number we add one onto the power of 10.
So the answer is:
lbs of oxygen are produced in the rainforest each year.
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
3² = 3 X 3 = 9
4³ = 4 x 4 x 4 = 64
= 2 x 2 x 2 x 2 x 2 x 2 = 64
The exact value in fractions are:
a) 1/9
b) 1/64
c) 1/64
<h3>What is a fraction?</h3>
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,

= 1/3²
3² = 3 X 3 = 9
= 1/9

= 1/4³
4³ = 4 x 4 x 4 = 64
= 1/64

= 1/
= 2 x 2 x 2 x 2 x 2 x 2 = 64
= 1/64
Thus.,
The exact value in fractions are:
