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
To write 9,000,000 in exponential form, we first need to determine the base and the exponent. Since 9,000,000 can be expressed as 9 x 1,000,000, the base is 10 (since 1,000,000 = 10^6) and the exponent is 7 (as there are 7 zeros in 1,000,000). Therefore, 9,000,000 can be written as 10^7 in exponential form.
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.
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.
10
The base is 7 and the exponent is 3.
