Write the following number in standard form

(4X10 4th power)+(3X10 3rd power)+(2X10 2nd power)+(5X1)=

43205

you are smart Joe and Reiny.

To write the given expression in standard form, we need to simplify it. Let's break it down step-by-step:

1) (4X10^4) = 4 times 10 raised to the 4th power
= 4 * 10,000
= 40,000

2) (3X10^3) = 3 times 10 raised to the 3rd power
= 3 * 1,000
= 3,000

3) (2X10^2) = 2 times 10 raised to the 2nd power
= 2 * 100
= 200

4) (5X1) = 5 times 1
= 5

Now, let's add all the simplified expressions together:

40,000 + 3,000 + 200 + 5

Finally, we can add these values to get the expression in standard form:

43,205

To write the given number in standard form, we need to simplify the expression and combine like terms.

(4 × 10^4) + (3 × 10^3) + (2 × 10^2) + (5 × 1)

Let's simplify each term separately:

4 × 10^4 = 4 × 10,000 = 40,000
3 × 10^3 = 3 × 1,000 = 3,000
2 × 10^2 = 2 × 100 = 200
5 × 1 = 5

Now, let's combine the simplified terms:

40,000 + 3,000 + 200 + 5 = 43,205

Therefore, the number in standard form is 43,205.
