Can someone also me and tell me what i needa do for these problems i’m confused , thxs

For c, it would be 111 because 10^2 = 100 and 10^1 is 10 and so on.

For 2a, it would be 100. Basically the exponent is how many zeros is after the one.

For 2b, 1000000000 or 10^9

For 2c, 100000000 or 10^8

2d, 100000 or 10^5

2e, 100000000 or 10^8

Hope this helps!
