5.67811 x 3.15576 = 17.918
10^5 x 10^7 = 10^12
move the decimal place over in the 1st part to make 1.79 and add 1 to the exponents to make 13
answer would be 1.791875241e13
Answer:
Cos b
Step-by-step explanation:
1/2[sin(a+b)+sin(a-b)]
1/2[sin a cos b +cos a sin b + sin A cos B - cos A sin B]
1/2[2sin a cos b]
sin a cos b
Answer:
I don't know about this thing
Answer:
3 letters can be arranged in 26*25*24 = 15600 ways
3 digits can be arranged in 10 * 9 * 8 = 720 ways
So the total number is 15600 * 720 = 11,232,000
So I agree with the number that you obtained
