Let's break down and solve the problems in the image you uploaded:

1. Put numbers into standard form:

The standard form for a number is written as: $a \times 10^n$ where $a$ is a number between 1 and 10, and $n$ is an integer.

• 6000 = $6 \times 10^3$

• 10000 = $1 \times 10^4$

• 5000000 = $5 \times 10^6$

• 240 = $2.4 \times 10^2$

• 260000 = $2.6 \times 10^5$

• 65700 = $6.57 \times 10^4$

2. Change these standard form numbers into ordinary numbers:

• $7 \times 10^3 = 7000$

• $4 \times 10^7 = 40,000,000$

• $1.3 \times 10^3 = 1300$

• $6.5 \times 10^7 = 65,000,000$

• $9.88 \times 10^5 = 988,000$

• $8.92 \times 10^7 = 89,200,000$
