98x10
Nine to the fourth power is written as 94, and is expanded as 9 x 9 x 9 x 9.
The expanded form of 3.4 is 3 + 0.4. In decimal notation, each digit's place value is a power of 10. The 3 is in the tens place, representing 3 * 10, and the 0.4 is in the tenths place, representing 4 * 0.1. Therefore, the expanded form is 3 * 10 + 4 * 0.1.
To write a number in expanded form, you first have to divide that number by a power of 10 that produces an answer where the greatest place value digit is units. In this case, we can divide by 10,000 to get 2.5. The next step is to express the power of 10 we used alongside the number as a multiplication. We divided by 10,000 which is the fourth power of 10 or 104. Thus 25,000 in expanded form is 2.5x104

43 = 64
124 = 20,736
10 raised to the power of -1 is 0.1
it would be 7 raised to the third power for exponential form and 7x7x7in expanded form and 343 in standard form .
6.4*104 = 64,000
