Question

it says use the table to rewrite the expression you wrote for problem 2. rewrite that expression so that both terms are written with the same exponent number 4. says use the distributive property simplify the expression you wrote for problem 3.number 5. says write your expression as the product of a decimal times a power of 10.number 6 says write your solution in scientific notation and number 7. says Evaluate (7.4 x 10^15 -- (9.9 x 10^13number 8 says Evaluate (8.9 x 10^5) + (6.5) x 10^6

Answer 1

7)

Given data:

The given expresson is a=7.7x10^15-(9.9x10^13)

The given expression can be written as,

a=770x10^13-9.9x10^13

=(770-9.9)x10^13

=760.1x10^13.

8)

Given data:

The given expresson is b=8.9x10^5-(6.5)x10^6

The given expression can be written as,

b=8.9x10^5-65x10^5

=(8.9-65)x10^5

=-56.1x10^5
