Ihave 2 questions, what is the smallest power of ten that exceeds 89,876,230,128,970?

question 1 options:

a. 10^11

b. 10^14

c. 10^15

d. 10^12 what is the smallest power of 10 that exceeds? 981 44/61

question 2 options:

a. 10^3

b. 10^4
c. cannot be found

d. 10^-2

Question 1:

For this case we have the following amount:

On the other hand, the exponents of the given options are positive, so we must run the decimal as many spaces to the right as the exponent indicates.

Thus, it is observed that the power that exceeds the given quantity is:

Question 2:

We have the following expression:

We have to

So, the correct option is

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
