Question

Find

(2.2 x 107)(5 x 108)
(2.5 x 103)(8.8 x 105)
expressed in scientific notation.

Answer 1

To express the given expressions in scientific notation, multiply the numerical parts and add the exponents.

Step-by-step explanation:

To express the given expressions in scientific notation, we need to multiply the numerical parts and add the exponents. Let's solve each expression one by one:

1. (2.2 x 107)(5 x 108)

Multiplying the numerical parts: 2.2 x 5 = 11

Adding the exponents: (107) x (108) = 1015

So, the result is 11 x 1015.

2. (2.5 x 103)(8.8 x 105)

Multiplying the numerical parts: 2.5 x 8.8 = 22

Adding the exponents: (103) x (105) = 108

So, the result is 22 x 108.

Answer 2

(2.2 x 107)(5 x 108)(2.5 x 103)(8.8 x 105)=
(235.4)(540)(257.5)(924)=
30,244,709,880=
3.024470988 x 10¹⁰
