Pls 23 points write 2.5 × 10^-5 in standard notation
what did the exponent tell you about the direction to move the decimal?
what does the negative exponent tell us about the number?

the negative exponent means that the decimal move to the left so the answer is 0.000025.

Step-by-step explanation:

2.5--->0.000025

1,918

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
