10-4 x 10-5 = 10-9.
4 x 10-5 = 0.00004
It is: 4/5 times 10 = 8
4 and 5/5 is the same as 5 so 10*5 = 50
To find how many times larger (4 \times 10^{12}) is than (8 \times 10^{7}), divide the two numbers: [ \frac{4 \times 10^{12}}{8 \times 10^{7}} = \frac{4}{8} \times \frac{10^{12}}{10^{7}} = 0.5 \times 10^{5} = 5 \times 10^{4}. ] Thus, (4 \times 10^{12}) is (50,000) times larger than (8 \times 10^{7}).
2/5 times 3/4 = 3/10 in simplest form
4 x 10-5 = 0.00004
40= 10 times 4 10 is breaken down to 2 times 5 bring down the 4 to get 2 times 5 times 4
It is: 4/5 times 10 = 8
4 and 5/5 is the same as 5 so 10*5 = 50
To find how many times larger (4 \times 10^{12}) is than (8 \times 10^{7}), divide the two numbers: [ \frac{4 \times 10^{12}}{8 \times 10^{7}} = \frac{4}{8} \times \frac{10^{12}}{10^{7}} = 0.5 \times 10^{5} = 5 \times 10^{4}. ] Thus, (4 \times 10^{12}) is (50,000) times larger than (8 \times 10^{7}).
How many times does 5 go into 20 ?
To find the product of the factors for (5 \times 5 \times 10 \times 10), first simplify the expression. This can be rewritten as (5^2 \times 10^2). Since (10) can be expressed as (2 \times 5), we have (10^2 = (2 \times 5)^2 = 2^2 \times 5^2). Therefore, the entire expression simplifies to (5^2 \times 2^2 \times 5^2 = 2^2 \times 5^4), which results in the product (4 \times 625 = 2500).
The H+ concentration is 10 times higher at pH=4 than at pH=5, according to the formula definition:[H+] = 10-pHSo 10-4 = 10 * 10-5 that's why, you see!
2/5 times 3/4 = 3/10 in simplest form
4
3.45 x 10^1
10x = 4 x = 4/10= 2/5 = .4
