Eight times.
It is: 2^8 times 5 = 1280
It is: 2*2*2*2*2*2*2*2*5 = 1280 or as 2^8 times 5 = 1280
As a product of its prime factors: 2*2*2*2*2*2*2*2*5 = 1280 or as 2^8*5 = 1280
As a product of its prime factors: 2*2*2*2*2*2*2*2*5 = 1280 Or as: 2^8 times 5 = 1280
If 5 packets of tea cost Rs 800, then the cost of one packet is Rs 800 / 5 = Rs 160. To find out how many packets can be purchased for Rs 1280, divide Rs 1280 by the cost of one packet: Rs 1280 / Rs 160 = 8 packets. Therefore, 8 packets of tea can be purchased for Rs 1280.
It is 4 times 320 = 1280
(160 × 8), (256 × 5), (320 × 4), (640 × 2)

2^8 x 5 = 1280
(including each only once) 2, 52^8 x 5 = 1280
To find the first term and common ratio of a geometric progression, we can use the formula for the nth term of a geometric sequence: (a_n = a_1 \times r^{(n-1)}). Given that the 6th term is 160 and the 9th term is 1280, we can set up two equations using these values. From the 6th term, we get (a_1 \times r^5 = 160), and from the 9th term, we get (a_1 \times r^8 = 1280). By dividing the two equations, we can eliminate (a_1) and solve for the common ratio (r).
The nearest 10 to 1275 is 1280. When rounding to the nearest ten, you look at the last digit, which is 5. Since 5 rounds up, you add 5 to 1275, resulting in 1280.
