00:00:00.810 --> 00:00:09.450
The Sun is about 10 times 10 times 10 times 10 times 10 times 10 times 10 times 10 miles away from Earth.
00:00:10.090 --> 00:00:16.450
Write the distance in exponential form and then evaluate it, giving your answer in millions of miles.
00:00:17.190 --> 00:00:28.760
So to take this and put it in exponential form, we have to know how many 10s there are: one, two, three, four, five, six, seven, eight.
00:00:29.300 --> 00:00:37.260
So we can write this as 10 to the eighth power because that’s what the exponent represents — how many times it’s being multiplied to itself.
00:00:37.760 --> 00:00:39.290
Now, it says to evaluate it.
00:00:39.720 --> 00:00:47.210
So essentially, we can either multiply 10 to itself eight times or plug in 10 to the eighth power on our calculator.
00:00:47.830 --> 00:00:50.360
And here we have 100000000.
00:00:50.990 --> 00:00:58.760
And a little trick is that if we multiplied eight 10s together, then we should have eight zeros.
00:00:59.000 --> 00:01:00.710
So maybe, we wouldn’t need a calculator.
00:01:01.180 --> 00:01:04.650
So here, we have 100000000 miles.
00:01:05.080 --> 00:01:09.380
But it says to write our answer in millions of miles.
00:01:10.030 --> 00:01:14.680
Here, we can see our number separated by the millions, the thousands, and the hundreds.
00:01:15.190 --> 00:01:19.470
So we have 100000000 of miles.
00:01:20.130 --> 00:01:27.250
So to answer our question, we were supposed to write it in exponential form and then evaluate it and giving our answers in million of miles.
00:01:27.680 --> 00:01:31.070
So in exponential form, it’s 10 to the eighth power.
00:01:31.630 --> 00:01:35.620
And then after evaluating it, we get 100000000 miles.
