Answer:

1.2 * 10^14

Step-by-step explanation:

Do 2*6 = 12

Do 10^5 * 10^8 = 10^(5+8)=10^13

Multiply the two answers together: 12 * 10^13

Write in scientific notation: 1.2 * 10^14

Solution:

Before we begin solving, I suggest reviewing a rule about multiplying exponents.

Rule about multiplying exponents:

  • Rule: If the base of a number is multiplied with the same base, the exponents will add.

Now, let's solve for the answer.

Open the brackets of both expressions.

  • (2 x 10⁵) x (6 x 10⁸)
  • 2 x 10⁵ x 6 x 10⁸)

Simplify 2 x 10⁵ x 6 x 10⁸.

  • 2 x 10⁵ x 6 x 10⁸

Add the exponents as per multiplying exponent rule

  • => 2 x 6 x (10⁵⁺⁸)
  • => 12 x 10¹³

Hence, the answer is 12 x 10¹³.
