Simplify the expression. (0.4x10^-6)(0.7x10^-2)

Mathematics
1 answer:

Answer:

2.8 ·  10^(-9)

Step-by-step explanation:

I'd suggest you do this problem through two separate multiplications:

First, 0.4·0.7 = 0.28, or 2.8 · 10^(-1)

Second, 10^(-6) · 10^(-2) = 10^(-8), and so the final result is

2.8 · 10^(-1) · 10(-8)  =  2.8 ·  10^(-9)

Please note:  negative exponents (such as -9, above) should be enclosed in parentheses for added clarity.

soldier1979 [14.2K]

Answer:

first term = 2 ...(given)

second term = f (2) = f (2-1) * 5 = 1 * 5 = 5. .....[according to the formula f(n) = f (n -1) *5 ]

third term = f (3) = f ( 3 - 1 ) * 5 = 2 * 5 = 10

fourth term = f (4) = f (4 - 1) * 5 = 3 * 5.= 15

fivth term = f (5) = f ( 5 - 1) * 5 = 4* 5. =20

5b - 5 - 126 - 7<br> I need steps please and thank you
MA_775_DIABLO [31]

Answer:

5b - 138

Step-by-step explanation:

Alright let's break it down.

First, you can see that each constant (5,126,7) have negatives in front of them. SO you are going to subtract each one of them.

When subtracting negatives it's basically just adding them together. How to do it is simply adding:

5 + 126 + 7

Then you get 138.

BUT, it was negative numbers. So it's actually -138.

Then bring back the 5b and your answer is:

5b - 138

Mark brainliest if you can :D
