10^-7
= 0.0000007
7^3
7,000,000,000 or 7 billion.
1*10-7
You multiply the exponents. For instance (23)3 = 29 : (54)1/2 = 52: (7-2)5 = 7-10
10 with an exponent of -6 = 4
the answer is 430,000,000 if the exponent is positive ;)
The base and exponent form a pair. You can chose any positive base and that will determine the exponent.243 = 49^1.5 that is base = 49, exponent = 1.5)or 243 = 10^2.5353 (approx) or 243 = 7^3.
Power = 5 = exponent. That is, exponent = 5.
10
Shift 7 decimal places to the right, so the exponent for base 10 is -7. Therefore, we have 7.28 x 10-7, which actually has 3 sig fig.
The base is 7 and the exponent is 3.
7 to the sixth power in exponent form is 76
