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
4 and 5/5 is the same as 5 so 10*5 = 50
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
10x = 4 x = 4/10= 2/5 = .4
5 goes into 50 10 times.
4/5 * 10/13 = 40/65 = 8/13.
six
5+5+5+5=20 or 4+4+4+4+4=20 Try adding 5 four times. 5+5=10 10+5=15 15+5=20 Or try adding 4 five times. 4+4=8 8+4=12 12+4=16 16+4=20
