Question

2.5 × 10^4 standard form

Answer 1

10^4 means to multiply it by 10 4 times.

2.5 * 10 * 10 * 10 * 10

We can group the 10s to make it a little easier to solve.

2.5 * (10 * 10 * 10 * 10)
2.5 * 10000

Then, we can carry on multiplication as normal.

2.5 * 10000 = 25000

2.5 * 10^4 in standard form is 25,000.
Hope that helped =)
