Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
The product of the expressions 2 × 10⁵⁸ and 2 × 10⁻²³ in the scientific notation will be 2 × 10³⁵.
<h3>What is multiplication?</h3>
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expressions are given below.
2 × 10⁵⁸ and 2 × 10⁻²³
Then the product of the expressions will be
(2 × 10⁵⁸) × (2 × 10⁻²³) = 2 × 10⁵⁸⁻²³
(2 × 10⁵⁸) × (2 × 10⁻²³) = 2 × 10³⁵

False , no that is not right ... It is incorrect
45+5.25n>108
-45 -45
————————
5.25n > 63
Divide both sides by 5.25
n>12
