To multiply something by a power of ten, as here, add 4 zeros after the nine (since the power is 4). In the case of a decimal (such as 9.14 times ten to the power 6), move the decimal point (in this example) six positions to the right, filling out with zeros where required.
It is x1 which is x.
8.23 x 109 = 8,230,000,000
It is: (x-y)4
If you are trying do find out x it's 2. 2 to the fourth power equals sixteen.
Well, 10 = 2 x 5, so 10^4 = (2 x 5)^4 = (2^4) x (5^4). The carat[^] symbol means to raise to the power of.
Nine to the fourth power is written as 94, and is expanded as 9 x 9 x 9 x 9.
x to the ninth power OR x to the 9th power OR x^9
81 3² x 3² = 9 x 9
9^(4) = 9 x 9 x 9 x 9 = 81 x 81 = 6561
4.61 x 106
Multiply 9 by itself three times (9 x 9 x 9) to find out. That's what the third power means. For the fourth power, you'd multiply again.
7.4 x 10-4 = 0.00074
It is x1 which is x.
8.23 x 109 = 8,230,000,000
1, 3, 9 1, 3, 9, 27, 81 3 x 3 = 9 3 x 3 x 3 x 3 = 81
x to the 5th power times y to the fourth power
7 to the fourth power = 7 x 7 x 7 x 7 = 2401.
