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.
For 336=214.2(t+3) you first divide each side by 214.2. You would get 80/51=t+3, then you would subtract 3 from each side to get the final answer which is -73/51
For 336=367.2(t) you divide 367.2 on both sides, to get the final answer which is 140/153.
D, 7-7 = 0
1-1 = 0
0 x 0 = 0
Solve what is in parenthesis first (5-9) = -4
Solve exponents next -4^3 = -64
Divide next
= -32
Lastly, subtract and resolve the negatives which become a positive number 125 - (-32) = 125 + 32 = 157
