When multiplying numbers with powers, you just add the powers together.
10-6 x 107 = 101
101 = 10
(6)3 x (6)7 = (6)10
3.86 times 10 to the power of -7 equates to 0.000000386
7 to the power of 8
The answer is 2,821,109,907,456
7 times 10 to the negative 6 in words is: seven millionths
(6)3 x (6)7 = (6)10
It is: -7*10^6 is equivalent to -7,000,000
3,376
6
You would write 7x7x7x7x7x7 as 7^6 (the ^ means to the power of, 7^6 is the same as 76. You would do this because there are 6 sevens there, and 7^6 means 7 times t times 7 times 7 times 7 times 7.
7*7*2*2*5*3 =(7*7)*(2*3)*(2*5) =49*6*10 =(50-1)*6*10 =(50*6-6)*10 =(300-6)*10 =294*10 =2940
3.86 times 10 to the power of -7 equates to 0.000000386
3 times 10 to the 8th power divided by 7 times 10 to the negative 7th power equates to: 4.28571428571
7 to the power of 8
The answer is 2,821,109,907,456
10 x 7 + 6 = 76
7 times 10 to the negative 6 in words is: seven millionths
