What is Number system?

A number system is defined as a system of writing to express numbers.

The given expression is (4.3x10⁸)x(2.0x10⁶)

We need to express  it in scientific notation

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

Firstly let us multiply four point three with two point zero

4.3×2

Which given 8.6

Now 8.6x10⁸x10⁶

When the bases are same then the powers will be added

8.6x10¹⁴

Hence, 8.6x10¹⁴ is the value of (4.3x10⁸)x(2.0x10⁶) in scientific notation.

Answer 2
Answer: First, you would multiply 4.3 and 2.0 together to obtain 8.6. After that if both of the numbers have 10 to the power of whatever number, you can add the exponents together. In this case, you would get 14. Your final answer is 8.6x10^14.

Answer:

d. 17.5 and 28 units

Step-by-step explanation:

An area of a rectangle is length times width. 8x times 5x = 40x^2. 40x^2 is eqaul to 500. After dividing by 40 and taking the square root of the quotient, x is approximately 3.54. 5 times 3.54 and 8 times 3.54 will yield approximately 17.5 and 28 units.
