Step-by-step explanation:
First evaluate the expressions in parenthesis;
-7+5 [(-3-2)^2 +(2^3 -40)]
-7+5 [(-5)^2 +(-32)]

-7+5 [-7] Multiply 5 by -7
-7 + (-35)
-42 This is the answer.
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
